Marie’s story: Bringing coding to kids in Tottenham

Post Syndicated from Sophie Ashford original https://www.raspberrypi.org/blog/maries-story-bringing-coding-to-kids-in-tottenham/

We love hearing from members of the community and sharing the stories of amazing young people, volunteers, and educators who are using their passion for technology to create positive change in the world around them.

Marie is a force of nature. As the founder of Breadline London, a grassroots community project in Haringey, she has spent years supporting families with essential services — she’s run a food bank, offered budgeting advice, and hosted well-being workshops. But when she heard about Code Club, she saw another way to help local children: by giving them the skills to shape their futures.

From community support to coding

Marie had no background in tech, but that didn’t stop her. She knew that many families in Tottenham couldn’t afford extracurricular activities like coding classes, and she was determined to change that.

“I’ve wanted a coding club for children, children in Tottenham, because that’s not something that is actually here,” she explains. “Unfortunately for us, we are on the very high end of poverty… and some of our children in this area don’t get the opportunity to attend things like coding club.”

With the support of Haringey Giving and the Raspberry Pi Foundation, Marie launched her Code Club at Tottenham Community Sports Centre. She started from scratch, learning alongside the kids, attending free training at the Raspberry Pi Foundation’s headquarters in Cambridge, and soaking up everything she could about coding.

“I don’t know anything about coding. Nothing. But going to the training days, it was so inspiring. I got so excited thinking, these are the things I can hopefully share with the children.”

Creating a space to experiment

Marie’s club is more than just learning how to code — it’s about teamwork, creativity, and confidence.

Marie helps a young learner with a coding task in her Code Club.

“They need to learn these skills outside of a school environment, outside of a place where it’s really structured. I want them to come in, experiment, make things up as they go along. Sometimes they follow instructions, but mostly, they just try things out.”

She also sees her role as a mentor, even if the kids sometimes know more than she does!

“Most of the children know more about coding than I do. So for me, it’s just about encouraging them: ‘What’s next? What else can you add to your project?’ And helping parents understand that they need to let the children create what they want to create, not just steer them.”

Discovering Coolest Projects

Marie’s journey didn’t stop with Code Club. When she learnt about Coolest Projects, a global showcase where kids celebrate what they’ve built with code, she knew she had to take her club to one of the in-person events.

Marie helps a young learner with a coding task in her Code Club.

“I was in Cambridge when I first heard about it, and this fabulous young woman spoke about Coolest Projects. I just felt so excited to take the children somewhere that’s just kids, just kids learning about coding and developing these amazing things. I even said, ‘Even if no one from my club comes, I’m going by myself!’”

Taking the kids to Coolest Projects was a game-changer. They saw what was possible, talked to other young coders, and left inspired.

“Next year, when we go again, everybody’s going to have a project. Seeing the kids’ faces when adults wanted to try their projects, it was so exciting for them!”

Making a change

Marie is proof that you don’t need to be a tech expert to start a Code Club — you just need passion and a willingness to learn.

Two educators are chatting at a workshop.

Marie’s message to others who are thinking about setting up a coding club but worry about their lack of experience is simple: 

“Start a [Code Club] because the children will help you to run [it]. They will help you. They will help each other. Don’t get put off running a coding club because you don’t know how to code. Because I don’t[…]and I love it.”

Marie’s story is a testament to what’s possible when someone believes in their community and takes action. She is creating opportunities for young people in Tottenham, giving them a space to learn, collaborate, and dream big regardless of their background. We can’t wait to see what her club achieves next!

Optimizing Financial Routines and Infrastructure with Banpará

Post Syndicated from Michael Kammer original https://blog.zabbix.com/optimizing-financial-routines-and-infrastructure-with-banpara/30815/

Banco do Estado do Pará (Banpará) is the main public financial institution in the Brazilian state of Pará. It is a mixed-capital company, organized as a multiple bank with the mission of generating value for the state of Pará. It currently has approximately 198 physical customer service units and is present in all 144 municipalities in the state.

The challenge

Until 2016, Banpará used a monitoring environment installed on a single physical server. This environment was centralized, not very scalable, and vulnerable due to the lack of updates to recent versions of the software used. Centralization created a critical dependency – if there was a server failure, the entire monitoring system would be compromised.

There was no integration with the tool that orchestrates the company’s routine activities (which also generated an alert and a need for proper support of the bank’s infrastructure) and there was also the issue of including the routines of the internal demand generation tool in the monitoring panel, which was done manually.

With each new routine created, it was necessary to open calls with the technical teams for inclusion in the monitoring plan, which were then entered into a list of tasks. This process, in addition to being time-consuming, was subject to human error and delays, which compromised real-time visibility of critical operations.

The lack of proactive and integrated monitoring in Banpará’s structure resulted in operational gaps that created real risks to the continuous functioning of banking operations.

The solution

Given the challenges posed, the project developed with Zabbix had as its main objective to recreate the monitoring environment in a virtualized, scalable and resilient way, without dependence on a physical server. From rebuilding the infrastructure to integrating it with critical banking systems, the primary requirements included the following:

  • Integration with existing systems
  • Intelligent data processing and analysis
  • Reduction of manual processes and operational dependency
  • Development of customized solutions
  • Reorganization of the technological infrastructure

After implementing and structuring Zabbix at the bank (with the help of Master Support, an official Zabbix Certified Partner in Brazil), the structure became modular, scalable, and resilient, aligned with best practices, and able to expand monitoring without compromising system performance as the bank integrated new routines and services.

The results

The modernization of monitoring environment with Zabbix brought immediate benefits for Banpará’s IT monitoring scenario, especially with regard to operational efficiency, reliability and process automation:

  • More than 2,000 monitored devices
  • Around 100,000 metrics collected
  • More than 26,000 active alerts in Zabbix
  • Automated coverage of around 2,300 routines
  • An estimated gain of 2,300 operational hours

The adoption of Zabbix as a monitoring tool at Banpará was a practical response to the need to modernize the bank’s IT infrastructure. The project contributed to the elimination of manual processes, reduction of operational time, and increased visibility over critical routines. It also enabled the monitoring of a greater number of services, with greater agility in identifying failures and supporting decision-making.

In conclusion

With the current structure, Banpará now has a more integrated monitoring system, adjusted to operational demands and with the capacity to monitor the evolution of the bank’s activities in an organized and secure manner.

Building HA Zabbix with PostgreSQL and Patroni

Post Syndicated from Patrik Uytterhoeven original https://blog.zabbix.com/building-ha-zabbix-with-postgresql-and-patroni/30960/

Running a monitoring platform like Zabbix in a production environment demands reliability and resilience. When your monitoring solution is down, you’re flying blind – and for many organizations, that simply isn’t acceptable. This post introduces a robust high-availability (HA) architecture for Zabbix, using PostgreSQL,  Patroni, etcd, HAProxy, keepalived and PgBackRest. Built on RHEL 9 or derrivates, this solution combines modern open-source tools to provide automatic failover, load balancing, and seamless monitoring, all while maintaining consistency and performance.

Architecture overview

The HA design consists of multiple layers working in tandem to maintain continuity even during node or service failures:

Database Cluster Layer

2 or more nodes form the PostgreSQL cluster, managed by Patroni and coordinated using etcd. At any given time, one node is the primary (read/write), and the others are hot standbys ready to take over automatically.

Consensus layer

etcd runs on the same nodes and acts as the distributed configuration store and coordination layer for Patroni. It ensures a consistent cluster state and enables safe failover decisions.

Load balancing layer  

Two HAProxy nodes provide a single point of entry for all clients (including Zabbix), routing requests to the current PostgreSQL primary. These nodes are monitored and coordinated via Keepalived to maintain a floating Virtual IP (VIP), ensuring seamless failover at the connection layer.

Backup layer

A separate backup server is responsible for running PgBackRest, which handles full and incremental backups, WAL archiving, and Point-In-Time Recovery (PITR). This server communicates securely with all database nodes over SSH.

Monitoring layer

Two Zabbix servers, running in active-passive mode, continuously monitor all layers of this stack including the HAProxy health, Patroni cluster role, and etcd status by accessing the PostgreSQL VIP for backend connectivity.

This multi-tiered setup ensures that no single failure be it a database, load balancer, or monitoring server brings down the monitoring platform.

Why HA matters for Zabbix

Zabbix depends heavily on its PostgreSQL database backend. Every metric, trigger, event, and alert is stored there. If PostgreSQL becomes unavailable, even briefly, data loss or monitoring blind spots can occur. That’s why introducing HA at the database layer is a crucial step when scaling Zabbix for enterprise environments.

While Zabbix itself supports HA at the application level, this architecture ensures that the database backend is also fully fault-tolerant, using modern consensus-based clustering with automatic failover.

Component overview

To achieve HA, we bring together several specialized components, each fulfilling a critical role in the system:

PostgreSQL

The relational database engine used by Zabbix. In this example setup, it runs on three nodes, forming a cluster managed by Patroni.

Patroni

Patroni is the orchestrator for the PostgreSQL cluster. It monitors node health, manages replication, promotes standbys when needed, and ensures only one writable leader exists at any time. Patroni leverages a distributed consensus store in this case, etcd but other DCS’s are possible to coordinate decisions across the cluster.

etcd

etcd is a lightweight and highly available key-value store used by Patroni to maintain the cluster’s state. It stores leader election data, health statuses, and locks. We deploy it as a three-node cluster, co-located with the PostgreSQL nodes for convenience, though this setup can be scaled independently if needed as etcd is very latency prone.

HAProxy

To simplify application connectivity, HAProxy acts as a load balancer in front of the database cluster. It monitors the role of each node using Patroni’s REST API and routes connections to the active primary server. If the leader fails, HAProxy automatically reroutes traffic to the new primary.

Keepalived

Keepalived provides a floating virtual IP address (VIP) across the HAProxy nodes. This VIP allows client systems, such as the Zabbix frontend, to connect to a single stable IP even if one HAProxy node fails.

PgBackRest

To protect the data itself, we use PgBackRest for full and incremental backups, as well as Point-In-Time Recovery (PITR). A dedicated backup server is included to pull and store archive logs and backups securely via SSH.

Zabbix server

Finally, we run two Zabbix servers in active-passive mode. Both are configured to connect to the PostgreSQL cluster through the VIP exposed by HAProxy. The Zabbix frontend is deployed on both nodes as well, ensuring continued accessibility through the load-balanced setup.

Topology at a glance

Here’s a simplified view of the architecture:

  • 2 or more database nodes (PostgreSQL + Patroni + etcd)
  • Two HAProxy nodes, each configured with Keepalived to manage a floating virtual IP
  • One backup node for PgBackRest
  • Two Zabbix servers pointing to the PostgreSQL VIP

All systems are tied together with consistent hostname mappings, time synchronization (Chrony), and service monitoring.

Notes:

  • PgBackRest is directly connected to all three PostgreSQL nodes, allowing it to archive WAL segments and pull backups regardless of which node is primary.
  • This design enables full standby backups and supports Point-In-Time Recovery (PITR).
  • HAProxy ensures Zabbix always talks to the current primary node, while Patroni and etcd handle automatic failover and cluster state management.

Design rationale

This setup prioritizes resilience and self-healing. If any single component fails a database node, a load balancer, or even a monitoring server the system continues to function.

Using Patroni with etcd ensures that failovers are handled automatically, without human intervention. HAProxy ensures client traffic is always routed to the current primary, while Keepalived ensures that this routing layer itself is highly available.

We opted for PgBackRest over simple scripts or base backups because it provides not just efficient incremental backups, but also full WAL archiving and point-in-time recovery, which are invaluable for both disaster recovery and debugging.

Lastly, we chose to integrate Zabbix itself into this HA design, treating it not just as a application but as a fully resilient service able to monitor itself, so to speak.

Real-world considerations
  • Resource planning: While our nodes run comfortably, scaling this setup to heavy workloads requires careful tuning of memory, I/O, and PostgreSQL parameters.
  • etcd placement: Although we run etcd co-located with the database nodes in this example, separating etcd onto dedicated infrastructure is ideal for large-scale environments. This avoids resource contention and preserves quorum in extreme failure scenarios.
  • Monitoring the monitors: Zabbix itself must be monitored. In our setup, each component including etcd, Patroni, and PostgreSQL exposes health endpoints that can be used by Zabbix agents or scripts to generate alerts on replication lag, cluster health, and failover events.

Conclusion

This architecture provides a solid foundation for running Zabbix in a fault-tolerant, production-ready environment. It not only ensures high availability for the database layer but also offers flexibility, observability, and operational safety.

Whether you’re running internal infrastructure monitoring or offering Zabbix as a managed service, adopting this type of HA setup removes single points of failure and gives you peace of mind — all using open-source technologies that are battle-tested and widely supported.

Exploring the Human Side of Software with Dylan Beatty

Post Syndicated from Michael Kammer original https://blog.zabbix.com/exploring-the-human-side-of-software-with-dylan-beatty/31320/

There are plenty of good reasons to attend Zabbix Summit 2025, but one of the most important is the fact that this year’s Summit will feature Dylan Beattie as a special guest speaker. A Software Development Consultant and Founder of Ursatile, Dylan is an international keynote speaker, and a long-time contributor to the open-source community. He’s also a Microsoft MVP and has created Rockstar, an esoteric programming language that started as an inside joke and ended up being featured in Classic Rock magazine.

At the Summit, Dylan will give a talk titled “Open Source, Open Minds. The Cost of Free Software.” We asked him about his beginnings in the tech industry, what drove the creation of Rockstar, and why communication is the key to successful software development.

Can you tell us a bit about your journey into software development? How did you get started, and was there any particular moment when you realized that you were on the right path?

Like a lot of folks in tech, I got started on the 8-bit home computers of the 1980s – mine was an Amstrad 6128, which came with a couple of fairly mediocre games, but it also had a BASIC and a LOGO interpreter, and I pretty quickly found out that writing little programs and trying to create my own games was way more fun than playing the games which were included with it. I graduated from that to a 286 PC with MS—DOS 5, Windows 3.1 – but I really wasn’t thinking about it as a career.

The turning point was when I was sixteen years old, and I was supposed to be going to university to study mathematics. Dad brought home a new 486 PC a couple of weeks before my final exams, I spent my study leave messing around on the computer instead of studying, and when I didn’t get the grades I needed for my university course I figured maybe that was a sign I should be studying computer science instead. I went to Southampton and got a bachelor’s degree in computer science, learned C, C++, Lisp, SQL, and HTML. I graduated right as the dot-com bubble was bursting but still managed to get a job building data-driven web applications, and I’ve never really looked back.

You talk a lot about the human side of software. Why do you think communication is such a critical skill in development?

One of the perennial challenges facing the craft of programming is that it can be a profoundly solitary activity. One person working on their own can create an app or a game, put it online, and share their creation with literally millions of people – no meetings, no emails, just one person cranking out code. But then you try to translate those coding skills into domains like banking, healthcare, aviation, domains where software quality can have a real, material effect on people’s lives, and you realize that the code is actually the easy part.

The ability to talk to people, figure out what they need, help them understand your own ideas; to create consensus and avoid misunderstanding? It’s way more important than being able to crank out code. The most expensive problems I’ve had to deal with in my career haven’t been bugs in the code, they’ve been misunderstandings about what the team is doing and why it matters.

How did you end up creating a programming language (Rockstar) that can do double-duty as rock lyrics?

Good question! So, there’s always been this trope of the “rockstar programmer” – these mythical, high-powered, hyper-productive developers who can crank out millions of lines of fast, flawless code – and about a decade ago there was a massive spike in recruiters putting out adverts for “rockstar programmers.” When somebody suggested on Twitter that somebody should create a programming language called Rockstar to really confuse recruiters, that gave me an idea.

Initially it was just a piece of comedy writing – a parody of a programming language specification. I wanted to see if it was possible to extract enough clichés from rock music to create a formal grammar for a Turing-complete programming language that read exactly like song lyrics. It turns out that the answer is yes! I published the parody spec on GitHub, it got shared on Reddit and Hacker News, and the whole thing snowballed from there. Eventually I had no choice but to actually build a Rockstar interpreter, which turned out to be way more difficult than I thought, but also a lot of fun. The latest version is online here  – it’s built in C#, compiles to native binaries for WIndows, Linux, and macOS, plus there’s a web assembly version on the website so curious folks can run Rockstar right in their browser without having to download anything!

Before taking on a speaking slot at this year’s Summit, how familiar were you with Zabbix? What has your experience of using it been like?

I’ve got to be honest – I’m not sure I’d ever heard of Zabbix before I was invited to speak at Zabbix Summit 2025, but that’s not unusual. I get invited to a lot of events that are focused around a particular technology or platform, and it’s a constant reminder of just how vast our industry is that somebody will organize a conference around a product I’ve never even heard of and attract literally hundreds of smart, curious people who want to share their own experiences and learn from each other. One thing about Zabbix which was particularly interesting to me when I started researching it was the licensing model. I think it’s a relatively unusual example of a commercially sustainable product or software that’s published under the Affero GPL license, so I’m really looking forward to chatting with other attendees about that and how that’s influenced their decision to use it.

You’re famous for your detailed and theatrical presentations – what makes a technical talk memorable to you?

A great talk is one that really connects with an audience, and the best way I’ve found to do that is to look for the little things that we all do every day that we’ve all learned just accept at face value, even when we have no idea why they work that way. Why is a capital “A” ASCII code 65 but a lowercase “a” is code 97? Why is validating email addresses difficult? Why is vertically aligning something in CSS such a big deal? There’s a good chance that a lot of folks in the audience have asked themselves that same question at some point, so the curiosity is already there. Tapping into that curiosity gets their attention, and then you can tell them the good stuff: the history, the stories, the personalities, the decisions.

There’s a lot of stuff in tech which feels kinda stupid, but none of it was designed to be stupid (well, except Rockstar!) Once you understand the context and the history, everything makes a lot more sense – and then at some point, maybe months later, you’ll hit a weird text encoding bug, or a problem with a system that won’t accept certain kinds of email addresses, and you’ll remember the talk. I get email from folks sometimes talking about how something from one of my presentations has helped them fix a weird bug years after they saw the presentation. That’s a great feeling.

Can you drop any hints about your presentation at this year’s Summit? What should audience members expect?

Sure! We’re going to talk about MIT, laser printers, software, Commander Keen, Doom, Quake, Netscape, the origins of the term “open source”, Linksys routers, WordPress, how the xz-utils backdoor nearly ended up compromising about half the computers on the internet – and a really cute story about a squirrel. It’s going to be awesome. I can’t wait!

Migrating from PRTG to Zabbix: A High-Level Guide

Post Syndicated from Patrik Uytterhoeven original https://blog.zabbix.com/migrating-from-prtg-to-zabbix-a-high-level-guide/30845/

For companies looking to migrate from PRTG Network Monitor to Zabbix, one of the most critical aspects is making sure a smooth migration of monitored devices and configurations. While there is no official tool to directly migrate between the two platforms, creating a bridge using custom export/import scripts allows for an effective and large migation. This blog post outlines a practical approach to achieving that migration based on the export/import methodology we at Opensource ICT Solutions previously implemented for one of our clients.

Why migrate?

While PRTG offers an intuitive interface and is popular for its ease of use, Zabbix provides:

  • Greater flexibility and scalability
  • Full open-source licensing
  • More powerful automation and templating
  • A robust API for integrations
  • Lower costs, especially since Paessler was sold to an investor

These features make Zabbix an attractive choice for teams looking to scale or standardize on open-source infrastructure.

Migration overview

The migration involves two key steps:

  1. Exporting PRTG device information
  2. Importing data into Zabbix

Because the two systems are conceptually and structurally different, we focused our scripts on migrating what is most transferable: device names, IP addresses, and interface types. SNMP versions or PRTG-specific sensor details were excluded or simplified where not applicable to Zabbix. PRTG, for example, will only export probes that have an OID that was not built-in in PRTG but added later, making our export incomplete. This does not mean we did a partial migration, it just means we have not included it in the automated approach.

Step 1: Exporting from PRTG

We developed a Python-based script that interacts with the PRTG API to extract monitored device data and export it to a CSV file. The script filters out irrelevant objects and organizes the output for easy Zabbix processing.

This creates a clean CSV, like this:

Device Name, IP Address, Interface Type
zabbix-server,10.0.0.10,agent
ServerA,192.168.0.2,SNMP
ServerA,192.168.0.2,agent
core-switch,192.168.0.1,SNMP

This file serves as a clean, structured inventory of monitored devices.

Note: SNMP version fields were excluded in the final export, as Zabbix does not currently display or rely on an SNMP version in the same way PRTG does.

Step 2: Importing into Zabbix

Using Zabbix’s API, we created an import script that reads the CSV and:

  • Creates host entries
  • Assigns them to the appropriate host group
  • Adds relevant interfaces (e.g., Agent,ILO,SNMP or a combination of …)

Each host is configured based on its detected interface type in PRTG.

On the Zabbix side, we used the Zabbix API to automate the creation of hosts, interfaces, and template assignment. The import script reads the CSV line-by-line and takes action based on the interface type.

Considerations and “gotchas”

  • Templates: We didn’t add templates, as there is no 1:1 solution – PRTG has a different concept and adding a standard template would be possible but probably not the best solution.
  • Host Groups: For ease of use and the limited time we had, we added all hosts in a temporary host group made for the migration. Although we do have scripts that take it out from PRTG and create it in Zabbix, in this particular migration it was not needed.
  • Permissions: The API token used in the import script must have sufficient privileges to create hosts.

What is NOT migrated

Because of fundamental differences between the platforms, the following are not directly migrated:

  • Historical data or sensor readings: Mainly because the customer had no hard requirement for it.
  • Custom PRTG notifications or dependencies: It was easier to manually re-create them.
  • Maps or dashboards: The Zabbix approach is so different that it was easier to recreate it manually (and improve).
  • Sensors: Zabbix is working with a different concept.

Post-migration tips

  • Validation: After the import, verify that each host is reachable and monitored correctly in Zabbix.
  • Discovery: Consider using Zabbix’s LLD (Low-Level Discovery) to dynamically find interfaces, disks, or other entities.
  • Housekeeping: Disable PRTG monitoring only after confirming Zabbix is fully operational.

Conclusion

Migrating from PRTG to Zabbix is not a one click operation, but with some scripting, planning, and experience from a partner like us, it can be done efficiently and with minimal disruption. The custom export/import scripts act as a reliable bridge between the two systems, allowing for a clean transfer of your monitoring inventory. From there, Zabbix’s automation and scalability features can help take your monitoring to the next level.

If you need assistance with the migration or want to ensure best practices for scaling and optimizing Zabbix, don’t hesitate to reach out to OICTS. We are a Zabbix Premium Partner operating globally, with offices in the USA, UK, Netherlands, and Belgium ready to help you every step of the way.

Expand your Knowledge at Zabbix Summit 2025

Post Syndicated from Michael Kammer original https://blog.zabbix.com/expand-your-knowledge-at-zabbix-summit-2025/31168/

October is just around the corner, and that annual shift into Q4 can mean only one thing – it’s almost Summit time! Zabbix Summit 2025 will take place on October 8-10 in Riga, Latvia at the Radisson Blu Hotel Latvija, and it’s shaping up to be the perfect blend of established traditions and fresh approaches – we’ve been at this for a (very lucky) 13 years now, and we’d like to think we’ve kept the aspects of the Summit experience that everyone knows and loves while adding a few twists! Here’s what you can expect for the price of admission:

Top-tier presentations from Zabbix leaders and experts

The learning begins with Zabbix Founder and CEO Alexei Vladishev’s keynote speech, which promises to be an “info drop” full of details about upcoming releases, new features, and what Alexei sees on the horizon for Zabbix. From there, it will be time for over 30 main stage speakers spread across two days of conference action. Some of the highlights include:

Presentations from Zabbix experts on topics like:

  • Turning playbooks into automated action plans
  • Streaming metrics for multiple tenants without chaos
  • Syncing systems painlessly
  • Maintaining control over massive amounts of Zabbix data
  • Detecting and responding to security threats before they escalate

Deep dives that will show you how to:

  • Spot the blind spots in large-scale networks (and fix them)
  • Keep tabs on Zabbix itself (after all, even monitoring needs monitoring)
  • Take full control of tag management
  • Use Zabbix Proxy to scale without breaking a sweat

Practical case studies, including:

  • Turning sensor data into insights with AI
  • Keeping SAP environments and multisite clusters in check
  • Transforming enterprise-level monitoring
  • Supercharging operations via migration projects
  • Making discovery, correlation, and AI work together for smart monitoring in action

Expect all this, plus inside information from the Zabbix team on the path to becoming a Zabbix partner and how Zabbix services can help you scale efficiently. As if that weren’t enough, this year’s Summit will also feature special guest Dylan Beattie! A Software Development Consultant and Founder of Ursatile, Dylan is an international keynote speaker, and a long-time contributor to the open-source community.

At the Summit, Dylan will give a talk titled “Open Source, Open Minds. The Cost of Free Software.” Expect stories about why developers choose to give their code away, what happens when they change their minds, the quirks of licenses and legalities, and the big question of whether open source can ever be truly sustainable.

Dedicated Dev and Community tracks

Created by developers and for developers, the Dev Track makes its debut this year and brings together some of the top minds on the Zabbix development team to cover topics as diverse as extending Zabbix Agent 2 with custom plugins, enhanced widget development, and template design best practices.

For attendees of a slightly less technical persuasion, the Community Track is there to facilitate author led discussions about community-driven content and resources, like the Zabbix Book. Assembled by longtime Zabbix enthusiasts Patrik Uytterhoeven, Brian van Baekel, and Nathan Liefting, the Zabbix Book will get its own breakout room, where Summit attendees can brainstorm in small groups about how to improve the book via new ideas and topics.

Hands-on workshops

The Summit experience has always been about finding opportunities to put theory into practice, and this year’s workshops showcase the latest features and use cases in action. Attendees will be able to dive into workshops on AI powered monitoring with Zabbix and ESP32, nested LLDs (low-level discovery), reducing alert noise, diagnosing performance issues with Diaginfo, and using Netflow integration via H5 Network. It’s a rare opportunity to confirm your knowledge retention by performing real-world tasks under the guidance of workshop hosts and their assistants.

Training and certification (yes, with discounts!)

A Zabbix Summit is the perfect place to get recognized as a Zabbix specialist or professional by taking part in Zabbix Certified Training sessions and exams at bargain prices. These one-day courses will be held from October 6 through October 13:

  • Automation and Integration with Zabbix API
  • Advanced Zabbix Database Monitoring
  • Advanced Zabbix SNMP Monitoring
  • Zabbix Certified Specialist Upgrade
  • Zabbix Certified Professional Upgrade

If you find yourself in Riga after the Summit, it’s worth your time to take part in the full Zabbix Certified Specialist course scheduled for October 13-17. Please remember that you can choose more than one training course and also keep in mind that you can attend the courses (without the 50% Summit discount) even if you’re not joining us at the Summit. You can register for all training sessions and exams here.

Networking and community building

 

A big part of what makes a Zabbix Summit a Zabbix Summit is the vibe – a big, global community coming together to catch up with old friends, welcome new members, and celebrate a certain open-source monitoring solution that brings us all together. That atmosphere of conviviality is exactly what makes a Summit such a one-of-a-kind networking opportunity. We’ve put together an open house visit and three evening events that are the ideal places to connect with like-minded monitoring enthusiasts, show off your skills, or get your company’s name in front of industry decision-makers.

This year’s Zabbix Open House on October 8 is your chance to see where the magic happens – drop by our offices and chat with our team members, grab yourself a coffee in our kitchen, and take part in a quiz that will teach even the most seasoned Zabbix fans a few new fun facts.

Dedication to digital education in Bangladesh: Meet Shajan

Post Syndicated from Sophie Ashford original https://www.raspberrypi.org/blog/dedication-to-digital-education-in-bangladesh-meet-shajan/

We love hearing from members of the community and sharing stories of amazing young people, volunteers, and educators who are using their passion for technology to create positive change in the world around them.

Today, we introduce Shajan, a digital storyteller and senior business advisor at the BBC, whose extraordinary personal and professional journey has led him to champion digital literacy for young people in Bangladesh.

Family roots in Bangladesh

Shajan is British-born, but his roots deeply connect him to Bangladesh. This connection was instilled by childhood holidays to Bangladesh, as well as his late father, who emigrated to the UK in the 1960s but always encouraged Shajan to maintain ties with the community he left behind. Shajan’s pull towards Bangladesh intensified after his father’s passing fifteen years ago. 

“I always thought I’d like to do something, carry on the work he left behind with efforts in building schools and supporting his local community.”

The memory of his sister Khela, who passed away at just 12 years old while in Bangladesh, also motivates Shajan. He says, “She was a really creative person, really into her arts and crafts and learning.”  

Khela’s loss fuels Shajan’s desire to do something specifically for the young people of Bangladesh, connecting with their potential for creativity and learning.

Setting off on a new path

Shajan’s 15 years of working for the BBC led him to discover the power of digital education. In 2015, he project-managed the BBC’s “Make It Digital” campaign, a UK-wide initiative addressing the National Digital Skills Gap. 

As part of this, he led partnerships with organisations like Code Club. 

“That experience showed me how digital tools could unlock creativity in young people and build their confidence.”

During his visits to Bangladesh, Shajan observed a widening digital divide. Young people, especially in rural areas, lacked access to basic internet and computers. Teachers faced heavy workloads, and many students needed to pause their education to support their families. Seeing no equivalent to Code Club in Bangladesh to inspire young people, Shajan felt he had to act. Before he knew it, he was requesting a six-month career break. 

“I said, ‘This is what I always wanted to do. If I don’t do it now, I will miss the opportunity.’” 

With the support of both the BBC and Code Club, Shajan packed his bags and moved to Dhaka, the capital city of Bangladesh.

Creating a movement

Shajan’s initial goal was to raise awareness and build a sustainable model for Code Club in Bangladesh. Recognising that teachers needed support to run clubs, Shajan’s strategy was to engage university students as volunteers. He organised a national coding festival, leveraging these student volunteers to connect with schools and prepare young participants for a Scratch-based project challenge. The event received lots of media attention, encouraging interest and inspiring a new generation of coders.

However, there were some hurdles that had to be worked around, including unreliable internet connections, limited access to computers, and unstable electricity supply. Beyond practical challenges, Shajan faced a crucial mindset shift. 

“Not everybody’s convinced yet that their children should be doing coding. For many families, generating immediate income takes precedence over digital education. Balancing the need to put food on the table with the long-term benefits of coding remains a constant battle.”

Despite these obstacles, Shajan’s efforts proved successful. Some of the creators from the 2016–2017 classes, now in their twenties, have pursued computer science and now share how Code Club helped them on their paths. He also organised an incredible exchange program, bringing creators and mentors from Code Club South Korea to Bangladesh for a seven-day visit. Despite not sharing a language, creators connected through the language of code, an experience Shajan describes as inspiring for the young people and adults alike.

A new chapter

Shajan’s focus now is to launch a Coolest Projects event in Sylhet, the place his father was born and a region he wants to focus on before taking Coolest Projects national as well.

He is actively engaging with teachers and student volunteers across the city, with strong support from Nooraiya Khan, an ICT Lecturer with a background in computer science. Nooraiya is working hard with Shajan to co-lead all Code Club activities in Bangladesh, bringing valuable expertise and shared passion to the movement.

Shajan believes the current digital landscape offers new opportunities. He is a strong advocate for the role of artificial intelligence (AI) in education, viewing it as a way to help bring opportunities to all young people. He plans to introduce AI-focused Code Club projects to Bangladesh, ensuring the next generation is prepared for a future driven by technology.

For Shajan, Code Club Bangladesh is “for everybody”. He wants to ensure that no child, especially girls and those from underserved communities, is left behind. He would welcome anyone interested in helping the young people of Bangladesh, including teachers, educators, tech professionals, and government bodies, to join Code Club Bangladesh’s journey.

If you’d like to support young people in your community to explore coding, why not start a Code Club? The team will support you every step of the way with resources, training, and a collaborative community.

Migrating Nagios to Zabbix: Lessons Learned

Post Syndicated from Nathan Liefting original https://blog.zabbix.com/migrating-nagios-to-zabbix-lessons-learned/30917/

Recently, a new customer of ours at Opensource ICT Solutions asked whether we could migrate their Nagios instance to Zabbix. Because Nagios and Zabbix are very different in their storage methods, we told them that we would have to investigate and see if we could come up with a viable solution. It wasn’t long until we found a way to do it and started building some script to get it done.

The customer’s wishes

  • No loss of any Nagios configuration data
  • Historic performance data migrated to Zabbix
  • Existing problems migrated from Nagios
  • Nagios XI to be disabled entirely, as the license is expiring

The customer was clear in their wishes – we needed to turn off Nagios, but without losing historic data. As such, they wanted all their old data visible in Zabbix instead of having Nagios running somewhere as a backup. This meant that a script had to be built to get that Nagios data out and into Zabbix.

The configuration data

The good part here is that it starts simple. When we dive into the Nagios configuration data, we clearly see that Nagios has hosts just like Zabbix. They just have a slightly different build than our usual Zabbix hosts. For example, we can see three different names for a host in Nagios:

  • Host Name
  • Alias = Host name
  • Display Name = Visible name

That immediately gives us a good way to hook up Nagios names to Zabbix host and visible names.

When we then take a look at the checks and how they are executed in Nagios, we also see similarities with Zabbix. In the end, both of them are monitoring solutions, of course. However, Nagios works more in a command execution kind of way, which is good for our migration. We can take this command and find an equivalent item in Zabbix. For example the check_icmp command can easily be translated into a simple check in Zabbix icmpping, icmppingloss, and icmppingsec.

For the check_tcp command we can do a similar translation. Making sure we use the simple check net.tcp.service whenever this command is executed on a Nagios host.

Because of the big differences between Nagios and Zabbix, this does mean we need to make some manual translations between the Nagios commands and Zabbix items. Depending on your Nagios instance, this could be a big task. Luckily for us, this was a smaller instance with only ICMP and TCP port checks.

The history (i.e. performance) data

Now that we know how to start creating our hosts and items, we need to understand how Nagios is storing its data. Zabbix has a big centralized MariaDB or PostgreSQL database, which makes it easy to parse through and work with our data. Unfortunately, Nagios instances use a different technique. Nagios stores data in .rrd (Round Robin Database) files and with it a .xml file to interpret the RRD file. The RRD files are not centralized like a Zabbix database, but they are more manageable in terms of storage size. We can see an RRD file per type of check in Nagios, which means we will have to grab the data from that file while understanding what it is going to belong to in Zabbix.

To see the data in the RRD file, we can use a special command line tool.

rrdtool /usr/local/nagios/share/perfdata/BeNeLux-Host-Name/Availability.rrd LAST --start -30d --end now | grep -v "nan"

Now we can clearly see that this specific RRD file above contains 8 columns, 7 with a performance value. The first column contains the timestamp in Unixtime, which is great because it will be perfect for storing in the Zabbix database. The other 7 columns in this file are different though, because we do not know what the value in the column belongs to. This is where the .xml file comes into play. The XML file belongs with the RRD file and contains details on what is included in the RRD file.

In this XML file we will find all of the required host information, which is great for creating the host in Zabbix. It also contains the check information, so we can also use this file to create the items in Zabbix. The biggest thing we will have to keep in mind is to make sure that the XML and RRD file match up in terms of number of RRD entries and columns. Column 1 in the RRD file will match with the first entry in our XML.

Let’s create a script

With the host, item and history data identified, we can start to create a script. In our case we decided to create a Python import tool. As Zabbix comes with some limitations in terms of which hostnames we can use (which are different from the limitations in Nagios), we need to sanitize our hostnames slightly.

Then all we need to do is parse through all the XML files and create new hosts in Zabbix through the Zabbix API.

It will be a very similar process for our items, as we parse through our XML file and create all of the required items in Zabbix through the API.

We can even create the triggers straight from the XML file by parsing through the different severities already set up in Nagios.

Once everything is created in Zabbix, the Python script can now start using RRDTool to parse through the RRD file, making sure to keep the XML file structure in mind when parsing through the columns.

This script can now create the hosts, the items, the triggers, and then import all of the data. We can see the hosts being created and data being imported.

The beauty of importing history data into Zabbix while the triggers are already created is then also seen below.

All of the triggers will trigger and be resolved based on the data imported, meaning that we can create problems with historic data. This means that not only do we have our historic data, but also all the problems with the correct duration as they are now discovered from the actual imported data.

To make this possible we can use the Zabbix sender tool. It has an option to include the timestamp upon every historic value imported.

Our Python script grabs the values from the RRD file and then converts them into a new _HOST_.sender file. This file will be sent to the Zabbix server using the Zabbix sender tool.

Looking at the file, we can see it contains only the name of the host, the unixtime stamp, and the actual value to send.

All we need to do is make our script send this file to the correct item in Zabbix.

Manual template and item creation

The last step will be our cleanup. We decided that we would start dirty with a one-on-one data import from Nagios. This means hostnames, item names, and trigger names are imported straight from Nagios. No templates will be created in Zabbix by the tool either, skipping the Zabbix best practice to use templates for all hosts.

We did this to make the initial import easier and not go overboard with scripting. It’s easier to have a messy Zabbix to clean up than to script everything perfectly in Python. Time is valuable.

What we did afterwards is create all the templates manually to take over the items as is from the hosts. For example, we can translate the ICMP ping and TCP stuff easily into a template.

After doing so, we do end up with some bad looking templates, but we can now start cleaning up.

We can also start creating normal trigger names and clean up…

…while changing our dynamic port names for something more expected as well.

And that’s it!

Reducing Alert Fatigue with Zabbix and China Pacific Insurance

Post Syndicated from Michael Kammer original https://blog.zabbix.com/reducing-alert-fatigue-with-zabbix-and-china-pacific-insurance/30913/

Headquartered in Shanghai, the China Pacific Insurance (Group) Co., Ltd. (CPI) is a Chinese insurance company that was established on the basis of the former China Pacific Insurance Corporation. CPI Group is the second largest property insurance company and the third largest life insurance company in Mainland China. It provides integrated insurance services (including life insurance, property insurance, and reinsurance) through its subsidiaries.

The challenge:

The overall data center operation structure of the company works along financial industry lines, with a two-site, three-center operation model. The total scale of China Pacific Insurance’s on-premises hosts is over 6,000, and the three centers add up to nearly 40,000 host devices in the production environment.

It’s an enormous amount of information to monitor, so any monitoring solution needs to significantly reduce the difficulty of overall alert analysis. The alert information provided by the mixture of cloud product components that CPI were using caused a serious case of alert fatigue for their operations and maintenance personnel, with some alerts taking as long as 4 months to process.

The solution:

The bank’s cloud platforms all had their own monitoring and alerting functions, but the configuration of value threshold and notification policies was not flexible enough. Zabbix’s ability to uniformly collect data while configuring triggers and alerting proved to be a game-changer.

In addition, when compared to cloud vendors whose solutions require adjustments to thresholds in each product component, Zabbix proved to be a much simpler and more cost-effective way to notify operators of only the most essential alerts.

The results:

In practice, CPI found that the Zabbix multi-index combined alert function eliminates 30% of invalid alerts. Thanks to this success, CPI now plans to transfer the Zabbix Data Transmission Service to their digital twin data center, so that the inspection of physical facilities and the impact analysis of the application system can be quickly displayed to their operations and maintenance personnel.

Conclusion

The team at China Pacific Insurance successfully built an intelligent operation and maintenance system covering a number of key modules such as automated operation and maintenance, intelligent monitoring, logging platforms, and container platforms – all with Zabbix at the core. They are currently exploring the cutting-edge integration of monitoring systems with LLMs, further advancing intelligent monitoring and observability solutions in the process.

From coder to mentor: Meet Isabelle

Post Syndicated from Sophie Ashford original https://www.raspberrypi.org/blog/from-coder-to-mentor-meet-isabelle/

We love hearing from members of the community and sharing stories of amazing young people, volunteers, and educators who are using their passion for technology to create positive change in the world around them.

Meet Isabelle, a youth mentor at a library Code Club, whose inspiring story tells how a passion for helping others and a love for reading led back to a childhood interest, shaping an unexpected and rewarding journey.

Isabelle celebrating her 18th birthday.

Saturdays spent at the library

Isabelle’s coding journey began around the age of nine. An avid reader, she regularly attended her local library in Stourbridge with her gran. When they saw there was a Code Club held on a Saturday morning, they both decided it might be a good skill for Isabelle to learn.

“I used to have like an entire folder of all the projects I’d completed. I’ve still got it somewhere in my room!” 

She quickly progressed through Scratch, Python, and HTML, even finding herself teaching the adults at the club at some points! But, as secondary school approached, her involvement naturally tapered off as she began to focus on her studies.

A return through volunteering 

In secondary school, Isabelle was looking for volunteering opportunities as part of her Duke of Edinburgh (DofE) award. Remembering her positive experiences at the library, and continued love of books, she initially considered volunteering there. Then, she had an idea.

“I suddenly thought ‘What if they still do Code Club?’ I really enjoyed it when I did it and I still remembered enough about it to help others. So, I felt like I could actually be useful instead.”

Isabelle reached out, and thanks to her gran’s long-standing connection with the library, she was remembered and welcomed back. What started as a three-month commitment for her DofE award soon extended to six. 

“I really looked forward to each session at the library and decided to stick with it for the whole time.”

Embracing the chaos and connection

Isabelle’s return coincided with the Code Club restarting. Stepping into a mentoring role, she quickly found herself in the thick of it. With five computers and a group of new young people, most of whom had no prior coding experience, the first sessions were a whirlwind. 

“It’s like the best kind of chaos. It doesn’t get easier as such. But it’s so fun meeting these new kids, they’re all different and they bounce off each other.”

She works closely with Lucy, the club leader, helping manage the flow of projects and supporting the children as they navigate everything from creating Scratch accounts to tackling challenging projects.

More than just code

While the technical skills are central, Isabelle emphasises that Code Club offers so much more. She’s seen shy children blossom, making new friends and becoming more involved.

“I think there’s the whole element of socialising as well. And beyond coding, kids develop essential IT skills, like learning how to use a mouse and keyboard. Something many who just use tablets and phones don’t know!”

Four years and counting  

Isabelle, now preparing to go on to further education, could not have predicted how her mentoring journey would turn out. What began as a three-month DofE requirement has turned into a four-year commitment. 

“It has just never been something that I thought ‘oh, I don’t want to do this anymore’. It’s just part of the weekly routine now. It’s been four years and it’s shocking how quickly it’s gone.”

Isabelle’s dedication hasn’t gone unnoticed. She’s built strong bonds with the staff and gained invaluable experience. She’s learned to organise, work in a team, and even run sessions independently, developing skills that will be invaluable for her future.

“I like the bond that I have with the staff and with Lucy. It feels great to be trusted that much and it has just been such a nice experience.” 

Lucy, Stourbridge Code Club leader and Library Assistant, shared her experience with the club and collaborating.

“Since Code Club offers so much more than just coding — confidence building, creativity, friendship, etc. — it plays an important role for children and young people in the community. The library is much more than just a place for books, and hosting Code Club here creates a welcoming space where young people can explore technology away from the classroom.”

“Isabelle has been absolutely fantastic both in supporting us with club admin as well as supporting the children with their coding! She understands the projects inside and out and is brilliant at not only solving problems, but also, importantly, encouraging the club to find ways of solving problems themselves. Our Code Club couldn’t have become what it is today without her input!”

Isabelle’s advice for future mentors

As Isabelle prepares to head off to the Bath Spa University to study media communications and publishing, she offers this advice for other young people considering becoming a Code Club mentor…”just go for it!” 

Isabelle admits to being anxious at times, but the experience has significantly boosted her confidence. 

“It built my confidence a bit more. You make friends along the way and you learn a lot of new things. And don’t worry if you don’t have a lot of coding experience. I don’t think you need it. I had a little bit but I was still basing it mainly off of reading the project instructions. And in all fairness, the instructions are really helpful!”

Mentoring at Code Club isn’t just about teaching, it’s about learning, growing, and connecting. It’s an opportunity to give back, build confidence, and discover the joy in supporting the next generation of digital creators. As Isabelle’s journey shows, sometimes the most rewarding paths are the ones you never planned to take.

Lucy shared why she thinks having youth mentors involved with Code Club is such an important dynamic.

“Youth mentors are great as role models and inspiration for children, and as a young person themselves they build such a great rapport with the club members. A mentor who’s closer to their age often feels more approachable, which helps create a comfortable and encouraging environment for them.”

If Isabelle’s story has inspired you, why not explore the world of coding? You can get started at home with over 250 free projects on the Code Club Projects website.

Creating a space for connection and code: Meet Seung Woo (Tony), Canada

Post Syndicated from Sophie Ashford original https://www.raspberrypi.org/blog/creating-a-space-for-connection-and-code-meet-seung-woo-tony-canada/

We love hearing from members of the community and sharing the stories of amazing young people, volunteers, and educators who are using their passion for technology to create positive change in the world around them.

Seung Woo, also known as Tony, is a 17-year-old student from Canada and the co-founder of his school’s Code Club, alongside his teacher, Kay. A curious and driven teen with big ambitions in computer science, Tony is not only passionate about technology, but also dedicated to building a safe, welcoming space where others can learn, explore, and grow alongside him.

Tony working on a programming project using a laptop.

A spark of inspiration

Tony’s fascination with computers started early, driven by his love of video games, coding, and, perhaps most memorably, his admiration for Tony Stark, the comic-book and film character who becomes the superhero Iron Man! The idea of building something powerful from scratch stuck with him.

“My whole life, I have been curious about the inner workings of a computer and my inspiration for coding is Tony Stark or Iron Man from the Marvel Cinematic Universe!”

Tony’s early coding journey wasn’t without its challenges. Finding the right resources was difficult, and staying motivated during tough moments was often hard without a support system.

“Like many others, I was independently taught, and during this time of independent learning I’d find many different roadblocks and challenges that I had to overcome alone. A big setback for me was finding the right resources in order to learn how to code. Another big obstacle for me was motivation. I would find myself losing interest in a project. I didn’t have the exterior motivation to help me push through the inevitable hardships that come with coding.”

That’s where the idea for a coding club began to take shape.

Creating a community of coders

Tony co-founded the Code Club at Collège Jeanne-Sauvé in December 2024 with that exact vision in mind — he wanted to provide a fun, collaborative, and welcoming environment where students of all skill levels could explore their love of technology together.

“I created the coding club to help everyone on their journey of computer science, no matter their skill level, and that is exactly what it is turning out to be. Finding resources is easier than ever with a teacher and all of the amazing members.”

Tony’s teacher and co-founder, Kay, shared why Code Club was the right fit for the school.

“I thought Code Club was the best way to start our club for a few reasons. The amount of coding language options was varied and appealed to the different learners in our club. It was also important for us to promote our club and let our community know about the presence of a coding club in our school, and Code Club helped us do so via their online presence.”

What makes Code Club special

For Tony, the secret ingredient behind his club’s success is simple: teamwork.

“Without teamwork, our club wouldn’t really be a club, it would simply be an ensemble of people coding in their own little cubicles, much like a stereotypical office job, and to me, that does not sound too enjoyable. Teamwork is our little secret ingredient in problem-solving and building motivation, we embrace it by creating a safe space where everyone can speak their minds without judgement!”

Members are free to choose their own learning paths. No matter the project, the atmosphere is always filled with laughter, energy, and curiosity.

“Coding should be something that is fun — not stressful like others may make it seem. Celebrating achievements, making short term goals, and problem solving with friends are all great ways that we make coding fun in our club. A second word would be teamwork. Without teamwork, our club wouldn’t really be a club.”

Teamwork, he adds, transforms what could be a solitary activity into something social and deeply motivating.

Looking to the future

Tony hopes the club will continue to grow, bringing more students into the world of coding and helping them feel at home in it. His story is a great reminder that learning to code isn’t just about computers — it’s about building community, confidence, and creativity.

“I wanted to create a space where everyone would be accepted and encouraged to learn more about coding and not be ashamed to ‘nerd out’ about this subject like I do very frequently. I’ve dreamed of creating a space that embraces this beautiful passion.”

If you’d like to explore coding, you can get started at home with over 250 free projects. 

For a little more support, or if you’re open to mentoring others, you can also join a Code Club. Check our website to find a club near you and become part of a like-minded and welcoming community.

Keeping Latvia Connected with Zabbix and LMT

Post Syndicated from Michael Kammer original https://blog.zabbix.com/keeping-latvia-connected-with-zabbix-and-lmt/30834/

LMT is a mobile GSM/UMTS/LTE operator in Latvia. Founded on January 2, 1992, it was the first mobile network operator in the country. In addition to providing mobile network and ISP services, LMT uses innovative technologies and solutions to develop and maintain a variety of IT solutions for public and private organizations. Currently, LMT is the largest telecommunications service provider in the country, with over 1,660 base stations and over 1.5 million users as of 2024.

The challenge

LMT utilizes a variety of monitoring solutions for a variety of purposes – from tools performing and monitoring ping responses to vendor-specific solutions and all-in-one tools such as Zabbix. LMT has 2 data centers, and since the vast majority of services delivered by LMT can be considered critical, most of the relevant infrastructure is duplicated across them.

Multiple Zabbix instances are used in the environment, including Zabbix 5.0 with MySQL database backend, Zabbix 7.0 with PostgreSQL, and TimescaleDB. Over 3,000 hosts with approximately 500,000 items are monitored by Zabbix.

The solution

Here is one example of how Zabbix is used to monitor switch cabinets in LMT data centers. Switch cabinets contain devices to measure the electric current, which support Modbus protocol and which can in turn be used to collect data.

Modbus monitoring was achieved by using Zabbix agent2 with the official Modbus plugin. This was combined with NetBox and GraphQL. NetBox was used as the source of truth, providing information about power feed and various electrical characteristics, such as voltage, amperage, utilization, phase, and more. The data was collected from NetBox via HTTP agent checks and GraphQL, and a JSON result was created by utilizing Zabbix preprocessing features.

The information collected from NetBox is combined with Modbus data collection utilizing Zabbix agent2. The data collected by Zabbix agent2 is preprocessed after the collection. The collected data is normalized and used by Zabbix low-level discovery features to automatically create Zabbix items and triggers for the available resources. Finally, the resulting data is visualized on Zabbix dashboards.

The results

Monitoring with Zabbix has made reacting to changes in the monitored power feed (detecting spikes, observing gradual power feed changes, etc.) a much simpler proposition for LMT, which in turn improves service for its millions of users.

In conclusion

Zabbix has proven itself to be an ideal solution for telecommunications clients, making it easier than ever to keep track of network health and performance, driving a more positive customer experience and greater revenue growth in the process.

Code, karaoke, and creativity: Meet Matthew

Post Syndicated from Sophie Ashford original https://www.raspberrypi.org/blog/code-karaoke-and-creativity-meet-matthew/

We love hearing from members of the community and sharing stories of amazing young people, volunteers, and educators who are using their passion for technology to create positive change in the world around them.

It’s especially inspiring to hear about young people who are not only passionate about technology, but who are also driven to share that passion with others. Meet Matthew, a 15-year-old creator and youth mentor at Code Club, who builds his own projects and inspires peers by organising hackathons.

Matthew’s early experience with coding 

Matthew’s journey into the world of coding began at a young age. His initial exposure was through Scratch at school in Singapore. From there, he began exploring self-learn platforms in his own time, getting to grips with HTML and basic web development.

His enthusiasm for creating led him to participate in a technology week in Year 6, where he took on a BBC micro:bit challenge. He dedicated his summer holiday to developing a token system that encouraged community recycling, using an ultrasonic sensor to award points for good behaviour. This early project showcased his knack for problem-solving and innovation.

What truly captivated Matthew was the possibility of combining the logical challenges of competitive programming with the joy of project creation.

Connecting with the community

Through YouthHacks, an initiative he co-founded to support teenage hackathon organisers, Matthew aims to expand access to hackathons across the UK (a hackathon is an event where individuals or teams work intensively over a relatively short time period to build software, hardware, or other kinds of technology). Matthew wants to offer advice and support, making it easier for young people to run their own hackathons. He puts a lot of time into ensuring that the content and atmosphere truly resonate with the participants.

“So, we made YouthHacks basically as an idea to be able to support these teenage organisers, you know, like hackathons for teenagers by teenagers.”

Matthew’s connection with the Raspberry Pi Foundation came from his keen interest in the hackathon community and a need for a local venue. Having previously toured the Foundation’s offices for a school robotics club, he decided to reach out when organising a satellite hackathon called Counterspell.

This initial collaboration led to further events at the Foundation, including Scrapyard Cambridge and, more recently, Cool as Hack.

Coolest Projects hackathon: A new approach to collaborative coding 

Cool as Hack was Matthew’s third event held at the Raspberry Pi Foundation offices. Unlike traditional hackathons with intense time pressure, this event, inspired by the spirit of Coolest Projects, aimed to be more relaxed and collaborative. 

“For this, people could bring in their own project scraps and then they could put it together with a team, finalise it, and then enter it to Coolest Projects.” 

The focus was on showcasing creativity and sharing projects globally, rather than competitive prizes. Everyone then entered their creations into the Coolest Projects online showcase.

Cool as Hack was a huge success. The atmosphere was incredible — there was even a karaoke session and a “swag shop” where participants could exchange tokens earned for innovative ideas or project milestones. This token system, designed by Matthew and harking back to his own recycling project from years ago, created a fun and engaging reward system.

Inspiring the next generation

Matthew’s drive to organise these events and encourage other young people to code stems from his enjoyment of project creation and the community aspect of hackathons. 

“Well, I suppose it links back to me enjoying making projects and when you attend a hackathon, it’s not a competition really. It’s more of a social event. So, you’re making a project and then you’re meeting quite a lot of coders, or even artists and musicians, and so many other people.”

Now a regular volunteer at the Raspberry Pi Foundation’s monthly Code Club in Cambridge, Matthew remains focused on encouraging others into tech. For aspiring young coders, he says that coding is far more diverse and creative than many might initially perceive, encompassing art, storytelling, and problem-solving. Matthew’s advice is simple: 

“Enjoy the process and as you learn new things you’ll realise that all of this is like super interesting, and that there are so many ways to make what you want. Just enjoy it and continue meeting new people and, yeah, be creative.” 

Matthew’s journey shows how an intro to computing at a young age can lead to an incredible amount of impact. With his continued dedication, he’s sure to inspire many more young minds to start on their own coding adventures.

If you would like to explore coding, you can get started at home with over 250 free projects.

What’s new in Zabbix 7.4

Post Syndicated from Arturs Lontons original https://blog.zabbix.com/whats-new-in-zabbix-7-4/30597/

With the release of Zabbix 7.4, Zabbix users will be able to further extend their existing resource discovery workflows and enjoy a wastly improved user experience when it comes to configuring Zabbix entities. In addition, the latest release introduces multiple dashboard and network map improvements which will further enhance the visualization of infrastructure and resources.

Host Wizard

Host creation can be somewhat confusing for Zabbix beginners. Creating a host and applying a template involves numerous steps – from creating a host and assigning it to a host group, to configuring appropriate host interfaces, applying a template, and editing template-level macros to adjust the default problem thresholds and filters.

The Host Wizard aims to simplify the host onboarding process by providing a step-by-step guide for creating and configuring a host.

The Host Wizard can be opened from the Data Collection – Hosts section

A new Host Wizard button has been added to the Data Collection – Hosts section. Once you click on it, you will first have to select the template you wish to apply on the new host. Only one template can be applied at a time, so if you wish to apply multiple templates on a single host via Host Wizard, you will have to do so via one template and one Host Wizard session at a time.

Under the hood, if we look at the template files, the templates have also received 2 new parameters: wizard_ready and readme. Only templates marked with wizard_ready: ‘YES’ can be selected in the Host Wizard.

Filter for and select the required template

After you have selected the template, you will be prompted to enter a host name and select host groups. You can create a new host or apply the template on an existing host.

Provide a host name and select host groups

The next steps include the deployment instructions. Depending on the selected template type, the Host Wizard will provide all of the required instructions to start monitoring the host with the chosen template.

The Host Wizard will provide the required host configuration steps

In the final Host Wizard steps, you will be prompted to add the required host interface, read the template notes, and customize the template-level macros.

Customize template-level macros to modify the default filters, problem thresholds, and other parameters

Nested low-level discovery rules and host prototypes

Low-level discovery rules have received major improvements in Zabbix 7.4. It is now possible to create nested low-level discovery rules, while host prototypes are now capable of discovering hosts of their own with low-level discovery.

A new type of prototype has been added to low-level discovery rules – discovery prototype. These prototypes are used together with low-level discovery macros to automatically create low-level discovery rules for resource discovery.

Discovery prototypes can now be created in low-level discovery rules

A new item type has been added for discovery rule prototypes – Nested. This type of discovery rule iterates through the JSON file received by the parent low-level discovery rule to discover child entities. For example:

[   {     "database": "db1",     "created_at": "2024-02-01T12:30:00Z",     "encoding": "UTF8",     "tablespaces": [       { "name": "ts1", "max_size": "10GB" },       { "name": "ts2", "max_size": "20GB" },       { "name": "ts3", "max_size": "15GB" }     ]   },   {     "database": "db2",     "created_at": "2023-11-15T08:45:00Z",     "encoding": "UTF16",     "tablespaces": [       { "name": "ts1", "max_size": "5GB" },       { "name": "ts2", "max_size": "25GB" },       { "name": "ts3", "max_size": "30GB" }     ]   },   {     "database": "db3",     "created_at": "2024-01-05T15:10:00Z",     "encoding": "UTF8",     "tablespaces": [       { "name": "ts1", "max_size": "12GB" },       { "name": "ts2", "max_size": "18GB" },       { "name": "ts3", "max_size": "22GB" }     ]   } ]

If we set the jsonpath preprocessing in the discovery rule prototype to JSONPath=$.tablespaces and set the low-level discovery macro to {#TSNAME}=$.name, the nested low-level discovery rule will create discovery rules to discover tablespaces for each database.

Low-level discovery rules are created from the discovery prototype

Inline form validation

Inline validation has been introduced with the goal of improving the overall user experience when configuring a variety of Zabbix entities. As of Zabbix 7.4, inline form validation is supported in:

  • Host configuration
  • Template configuration
  • Item configuration
  • Trigger configuration
Inline validation detects any configuration errors on the fly and displays a corresponding error message

With inline validation in place, users will now receive immediate feedback regarding any configuration mistakes they have made in the sections above. Configuring new entities, especially items and triggers with complex keys and expressions, is now faster than ever.

Frontend-to-server communication encryption

To further strengthen Zabbix communication flow security, Zabbix 7.4 introduces the ability to secure frontend to server communication with certificate encryption. The encryption must be configured from two sides, and the frontend setup now includes the options to enable and configure encrypted connections to the server.

 

Zabbix 7.4 introduces the ability to encrypt frontend-to-server connections

On the Zabbix server side, multiple new configuration parameters have been added:

  • TLSFrontendAccept – which incoming connections to accept from frontend
  • TLSFrontendCertIssuer – allowed frontend certificate issuer
  • TLSFrontendCertSubject – allowed frontend certificate subject
  • FrontendAllowedIP – frontend connections will be accepted only from addresses listed here if the parameter is set

New widgets and visualization improvements

Zabbix 7.4 introduces a new widget (Item card) and multiple visualization improvements for dashboards and network maps.

Item card widget

The new Item card widget behaves similarly to the existing Host card widget introduced in Zabbix 7.2. The Item card widget provides a customizable view of an item and its attributes, such as latest data together with a sparkling chart, error messages, interfaces, tags, triggers, and more. The attributes for display can be selected and ordered in the widget configuration.

Various item attributes can be displayed in the item card widget

Network map improvements

Network maps have also received multiple improvements, enabling new use cases and simplifying existing network map scenarios.

  • Map background images can now be scaled proportionally to the map dimensions
  • Map links now support link indicators based on item value thresholds
  • Map element icons can now be ordered when placed on top of one another
Item value thresholds can be defined for link indicators
  • Map element icons can now be ordered when placed on top of one another
  • Host group map elements will now take into account nested host groups when displaying host group-related information
  • Map link and element labels can now be hidden and only displayed on mouse hover
Map elements can be ordered on top of each other

Dashboard improvements

Zabbix 7.4 introduces multiple dashboard improvements to facilitate faster and smoother dashboard configuration.

The color picker in graph and pie chart widgets has been extended with the new palette color scheme in addition to the existing solid color scheme. Users can choose from the available palette color schemes. The new palette color schemes display the values within a data set in a more distinguishable way, while the existing solid color scheme displays the data set values in shades of the selected color.

The new palette color scheme is available in graph and pie chart widgets

Widget configuration changes are also displayed instantly in Zabbix 7.4 – there’s  no need anymore to apply the changes to see them reflected in the widget.

In addition, the default Global view dashboard has received an overhaul and now utilizes the latest Zabbix widgets to provide additional insights about the Zabbix instance.

The default Global view dashboard has received an overhaul

Other changes in Zabbix 7.4

Multiple smaller fixes have been introduced in Zabbix 7.4, such as new history functions, new macros, security fixes, and more:

  • Preprocessing results can now be copied directly to clipboard by using the “Copy to clipboard” button
  • All users are now allowed to manage their own media by default. These permissions can now be revoked in user role settings
  • A new Notifications section for customizing notification settings has been added under “User Settings”
  • Vault secret macros can now be resolved by either the Zabbix server or Zabbix proxy
  • A new icmppingretry simple check has been added to monitor host responses to ICMP ping with the ability to modify retries
  • New timestamp tracking history functions have been added
  • Multiple new macros added for item-value time tracking
  • Zabbix server/proxy automatically logs history cache diagnostic information when the history cache is full
  • Disabled items are now immediately removed from the history cache
  • It is now possible to manually clear the history cache for a specific item by its id with the history_cache_clear=target runtime command
  • Added support of Gmail OAuth authentication

New templates and integrations in Zabbix 7.4

Many of the existing webhook integrations have been refactored in Zabbix 7.4. The webhooks have been optimized for the best possible performance and include a variety of fixes:

  • Discord
  • GitHub
  • GLPi
  • Jira
  • Jira Service management
  • MS Teams
  • MS Teams Workflows
  • OTRS CE
  • PagerDuty
  • Slack
  • Telegram
  • Zammad

Zabbix and a Federal Government Agency

Post Syndicated from Michael Kammer original https://blog.zabbix.com/zabbix-and-a-federal-government-agency/30708/

Our Premium Partners at the ATS Group work with a large federal government agency in the United States. They primarily provide storage and compute-as-a-service for the agency, which relies on them to stay up and running at all times.

The challenge

The agency’s primary goal was to simplify their capacity and performance monitoring without extra costs. They had very strict regulatory and SLO oversight requirements that had to be met, especially when it came to capacity and performance.

There was no commercially available software that could accomplish everything they needed directly out of the box, but they still required a solution that was powerful and flexible enough to monitor almost anything.

The solution

Because the agency has several different data centers of different sizes, they use a distributed proxy set up, intense SLA reporting, a ServiceNow integration, a variety of internal integrations, and a monitoring solution provided by Zabbix that includes a predictive alerting setup.

The agency has plenty of software in the mix, but it primarily relies on storage, VMWare, and Kubernetes. They also have multiple satellite offices and data centers, so that in the event of a data center failure, another can come online with minimal downtime in between.

On top of that, they have over 30 metrics and more than a trillion data points across 10 major technologies that they need to measure, primarily from a regulatory perspective. Thousands of granular metrics needed to have solutions and reporting designed for them in Zabbix, including (for example) CPU cores and frequency, processor-to-core usage metrics, and virtualization ratios from hosts to virtual machines.

Their Kubernetes-based Openshift environment also needs to be monitored to exact specifications. Deployment took place via Helm Chart, with Zabbix components being installed as Kubernetes resources, node-level resources, and applications being monitored, while data was aggregated and sent to the Zabbix server.

Metrics are collected via the Kubernetes API and kube-state metrics, and the solution uses Prometheus-exported metrics or direct HTTP endpoint calls. When it comes to configuration, proxies and hosts are created in Zabbix to represent Kubernetes nodes and clusters, while templates and macros are configured to point to the Kubernetes API and kube-state-metrics endpoints.

The results

Thanks to Zabbix, the federal government agency in question has a solution that provides centralized monitoring of Kubernetes alongside other IT resources, supports application-specific metrics without requiring Prometheus endpoints, and offers plenty of flexibility to customize and scale.

In addition, Zabbix’s predictive alerting capabilities identify abnormalities in operational data and predictively alert the agency about anything that could potentially impact an application or service, which lets them meet SLAs, optimize user experience, and increase productivity.

In conclusion

Zabbix’s flexibility and ease of customization make it ideal for customers who need a single source of truth that can be relied on in even the most stringent regulatory environments.

Zabbix at the Netherlands Ministry of Infrastructure and Water Management

Post Syndicated from Michael Kammer original https://blog.zabbix.com/zabbix-at-the-netherlands-ministry-of-infrastructure-and-water-management/30681/

The Ministry of Infrastructure and Water Management is the Dutch ministry responsible for transport, aviation, housing policy, public works, spatial planning, land management, and water resource management. Created in 2010 following the merger of the Ministry of Transport and Water Management and the Ministry of Housing, Spatial Planning, and Environment, the ministry works to create an efficient network of roads, railways, waterways, and airways, effective water management to protect against flooding, and improved air and water quality.

The challenge:

The ministry needed a monitoring solution that could handle not only infrastructure monitoring, but also IoT devices responsible for monitoring water levels, water quality, temperature, and other data. The infrastructure components that needed to be monitored included Red Hat Satellite and Capsule servers, Red Hat Virtual Data Centers, Red Hat Identity management, Ansible automation platforms, and a wide range of custom IoT devices.

The solution:

The Red Hat Satellite and Capsule monitoring consists of one satellite, 6 server, and 15 satellite capsules for different environments, with approximately 2000 Linux machines connected to the satellite capsules. The machines retrieve their packages from the capsules and the capsules act as proxies that fetch data from the satellite servers. The capsules also manage the content packages and subscriptions for the machines.

For Red Hat satellite and Capsule monitoring, Zabbix performs capsule discovery via Low Level Discovery, which uses Http requests, which in turn collect data via the REST API. Each capsule’s content sync status is monitored and if the content sync fails, new packages are not installed. Connectivity between capsules and the satellite is also monitored by performing port checks, because capsules need to be able to connect to the satellite in order for the content to be synced.

Zabbix also discovers and monitors satellite repositories, checking both when the last sync was performed and the current sync status. Software subscriptions are also discovered and monitored and alerts are sent, with the severity of the alerts raised at the point when a subscription has only 30 days remaining.

Red Hat Virtual Data Center licences and identity management also benefit from the added flexibility that Zabbix brings to the table. Virtual DC licences must be present on ESX hosts, so situations where an ESX host with an active license has no VMS on it (or has VMS migrated to it) must be avoided, because that would mean that a license is being essentially wasted. Whenever a Zabbix trigger detects a problem, Ansible automatically attaches or detaches a licence to or from the ESX host, depending on the type of problem detected.

When it comes to Red Hat identity management, Zabbix discovers and monitors processes on the identity management platform (including identity management service status) thanks to the ability to extend Zabbix agent with user parameters.

Meanwhile, Ansible Automation Platform monitoring consists of monitoring for controllers. The Ansible Automation Platform API is used to discover the controllers, and each controller is checked to see if any jobs are running, their last seen time, their capacity, and their status. Sometimes controllers are disabled for maintenance and then re-enabled, so alerts are sent out for controllers that have been disabled for a longer time.

Ansible Automation Platform monitoring also includes monitoring decommission machines, which are assigned to a group instead of being immediately deleted. Zabbix monitors the grace period for the decommission machines and alerts users if the grace period is over, generating a warning if an Ansible host is disabled for seven days and then escalating it if the machine has been disabled for more than 14 days.

Zabbix also discovers and monitors configuration management jobs, and if a job fails it will attempt to restart it. If the issue is still not resolved, it gets escalated to the appropriate individual. These Ansible checks are primarily done via Http agents, from Zabbix servers or proxies.

Finally, in addition to infrastructure monitoring, Zabbix also monitors the health of IoT devices responsible for water levels, water quality, temperature, and other data. These devices are running Raspberry Pi modules and Zabbix Agent 2 is used to monitor the device status. Zabbix Agent 2 with a local agent database is used in cases where the agent is unable to send the metrics on these devices. Should a network outage happen, Zabbix stores the backlog data in the local agent database.

The results:

Trusting their monitoring to Zabbix has greatly improved processes at the ministry, saving time and money by making it easy to notice and fix issues before affected departments themselves were aware of them. In addition, having the latest historical data at their fingertips has been invaluable to the ministry’s technical teams during troubleshooting or when dealing with performance issues, saving everyone involved a great deal of time.

In conclusion

Zabbix’s flexible nature and its ability to integrate with popular platforms as well as custom devices made it the perfect “one-stop shop” for the ministry’s needs, consolidating all of their monitoring in a single pane of glass and giving them complete visibility into every layer of their infrastructure – while also integrating smoothly with their existing systems.

Let Zabbix be your Lucky Lady for Lotto Numbers

Post Syndicated from Janne Pikkarainen original https://blog.zabbix.com/let-zabbix-be-your-lucky-lady-for-lotto-numbers/30251/

Many years ago, maybe around 2017 or 2018, one of my ex-colleagues (Hi, Kevin!) said that I would probably even use Zabbix to come up with the winning lotto numbers. Just to strike back, I did exactly that with a small “easter egg” in Zabbix containing the lotto numbers – a quick bash script feeding the Zabbix item.

Let’s return to that topic, but use a Zabbix Script item type instead. Also, let’s take a look at few other details that help with monitoring.

Let’s create a host and a new template

To begin with, I created a new template and a new host. Here’s the host, nothing more needed than a name and my fancy template:

The template has only one item:

For the script, here’s what ChatGPT came up with. JavaScript is not my strongest skill, so for a fun little experiment this AI vibe coding should be good enough.

// Generate an array of numbers from 1 to 40
var numbers = [];
for (var i = 1; i <= 40; i++) {
   numbers.push(i);
}

// Shuffle the array using the Fisher-Yates algorithm
for (var i = numbers.length - 1; i > 0; i--) {
   var j = Math.floor(Math.random() * (i + 1));
   var temp = numbers[i];
   numbers[i] = numbers[j];
   numbers[j] = temp;
}

// Select the first 7 numbers from the shuffled array
var lotto = numbers.slice(0, 7);

// Optionally sort the selected numbers
lotto.sort(function(a, b) { return a - b; });

// Return the lottery numbers as a space-separated string
return lotto.join(" ");

So, that’s it! Well, almost – to stop Zabbix from coming up with new numbers all the time, here’s a very nice feature of Zabbix.

Custom intervals

If you set your Update interval to 0, you can use Custom intervals. This way, the new numbers will only be generated once per week every Monday at 8:00 to kick off your work week (assuming that your country has the lotto only once per week, of course).

Naturally, in the actual business world, this kind of exact scheduled monitoring can be extremely helpful as well. If you have something you don’t need to check all the time but only during business days and hours, or only on weekends, or only once per day, this is a handy way of doing it.

Does it work?

You know the answer — of course it does! Now when I search for “lotto”, click on “Latest data” and force the check to happen immediately by clicking on “Execute now”, this happens.

Time to dashboard it

I could peek at the values from Latest data, but that would be boring. With a dashboard, it’s a bit more entertaining…

I hope this post gave you some new ideas or maybe even introduced you to Script item type. If you win some major money with this trick, don’t forget to buy me a coffee!

Optimizing Incident Management with Zabbix and PagerDuty

Post Syndicated from Zabbix LatAm original https://blog.zabbix.com/optimizing-incident-management-with-zabbix-and-pagerduty/30114/

When monitoring environments, we sometimes need to rely on third-party tools to better manage functionality and optimize responses to alerts. Let’s explore how to integrate Zabbix with PagerDuty, a real-time incident management solution designed to improve the reliability of digital services, including best practices and configuration details.

What is PagerDuty?

PagerDuty is a real-time incident management platform designed to help IT teams react quickly to critical events. The tool helps organizations automate and manage incident response through a system of alerts, escalation, and coordination between teams. When a problem is detected in the system, PagerDuty notifies the responsible individuals and ensures that corrective action is taken quickly. This reduces downtime and improves operational efficiency. Integration with monitoring tools such as Zabbix makes it easy to identify issues before they impact users.

Some of PagerDuty’s key features include:

• Integration with monitoring tools (such as Zabbix)
• Notifications in multiple channels (email, SMS, calls)
• Automatic escalation of incidents to ensure agile responses
• Event analysis to improve the detection of recurring problems

How to integrate PagerDuty with Zabbix

In PagerDuty, go to “Services” and click on “Service Directory.” Create a new service.

Give it a proper name and description.

Accept the escalation terms and click “Next.”

On the next screen, select “Intelligent” and the “Auto-pause incident notifications” option, then click “Next.”

The next step is to add the Zabbix Webhook service, which will allow integration with Zabbix, and then click “Next.”

In Services > Service Directory, select the name of the service. In the “Integrations” tab, copy the integration token that is generated.

It is important to note that the PagerDuty webhook only shows the option of Zabbix versions 5.0 to 5.2, but it works correctly in later versions such as Zabbix 7.2, which was tested without any issues.

On Zabbix Server, go to Alerts > Media types > PagerDuty. Enter the integration token, the Zabbix URL, and select “Update.”

Send a test message to confirm that the integration is working correctly.

In the PagerDuty application, verify that the test alert was received.

To send notifications, you need to grant permissions to a user in Zabbix. Go to Users > Create User. In the “Media” tab, select PagerDuty as the notification method. Set the severity of the alerts you want to receive.

Subsequently, set up a Trigger Action in Alerts > Actions > Trigger Actions to define what types of alerts will be received (either by item or trigger) according to the needs of your team.

Best practices for integrating Zabbix and PagerDuty

• Customize notifications: Set rules to send only truly critical alerts, avoiding unnecessary notifications.
• Optimize escalations: Set up escalation rules so that alerts reach the right people at the right time.
• Monitor key metrics: Measure incident response times and adjust workflows as needed.
• Automate incident responses: Use PagerDuty’s capabilities to perform automated tasks in response to specific events.
• Notify about service failures: Use PagerDuty to start running recovery scripts, send notifications to the responsible teams, or even escalate the problem to a higher level if there is no solution in a stipulated length of time.

Conclusion

Zabbix’s integration with PagerDuty allows you to monitor the status of critical services in real time, even outside of working hours. This facilitates rapid incident response and improves your IT team’s ability to react.

This combination not only optimizes incident management but also helps minimize downtime, improve operational efficiency, and ensure the reliability of monitored systems.

With proper configuration and best practices, integrating Zabbix with PagerDuty can become essential for the proactive management of your technological infrastructure.

Build a Culture of Monitoring and Get Buy-In with Zabbix

Post Syndicated from Michael Kammer original https://blog.zabbix.com/build-a-culture-of-monitoring-and-get-buy-in-with-zabbix/30085/

In today’s fast-paced, interconnected IT world, simply waiting for something to fail before fixing it isn’t good enough. A proactive approach to monitoring, which aims to identify and address potential issues before they escalate into major disruptions, is a necessity rather than a luxury.

Here at Zabbix, we’ve got plenty of reason to believe that we offer the most flexible monitoring solution available on the market today. However, choosing the best monitoring tool for your organization’s needs is only half the battle – you also need to get buy-in from team members who may not understand the need for monitoring, may be fearful of and resistant to change, and may not be familiar with the technologies behind monitoring.

In this post, we’ll take a look at a few strategies you can use to help win over lukewarm or hesitant colleagues and build a culture of monitoring. We’ll also explore how choosing Zabbix for your monitoring needs can make each strategy a bit easier to implement.

Strategy 1: Explain the “why”

One of the first questions that you can anticipate during any change initiative is simply, “what for?” The ethos of “don’t fix what isn’t broken” runs strong in the tech community, and unless you go above and beyond to explain why monitoring matters, your team will remain skeptical.

Zabbix can help you make your case by providing you with the evidence you need to bolster your case. We’ve got plenty of testimonials available from tech communities worldwide (including PeerSpot, Gartner, and Capterra), and no matter what field you’re in or how big your team is, we’ve most likely got a case study or two available that shows how monitoring with Zabbix was a game changer for a company like yours.

All of this should help you explain the rationale for the change in an open and transparent way. When it comes to monitoring, sharing details on costs, expected benefits, and what will happen if no change is made will build understanding around why monitoring is necessary and why monitoring with Zabbix is the right answer for your team’s needs.

Strategy 2: Show your team what’s in it for them

One of the most effective ways to get employee buy-in for monitoring is by highlighting the benefits it will bring to individual employees. Show how monitoring can simplify their tasks, improve efficiency, and enhance their work experience, and give them concrete examples of how the technology can make their jobs easier or help them to deliver better results.

We recently had a large managed services provider (MSP) use our monitoring solution as a true “force multiplier”, allowing them to monitor their systems, automate tasks based on real-time events, and provide immediate responses to issues without manual intervention. Thanks to Zabbix, their engineers report higher job satisfaction thanks to no longer having to be “on call” at all hours to solve simple issues, while management has seen productivity skyrocket thanks to their team’s newfound ability to find potential issues before they become real problems.

Strategy 3: Turn important stakeholders into monitoring champions

Determine who monitoring will impact and who needs to be kept informed. This might be team leaders, IT staff, end users, and/or an executive sponsor. Getting input from these groups early on will help you anticipate needs and concerns, and you’ll also want to identify influential employees who are enthusiastic about monitoring and get them to help you promote it.

A great way to help them do so is by encouraging them to attend one (or more) Zabbix events – we’ve got free meetings, online meetups, regional conferences, or even our yearly Summit in Latvia. No matter where you happen to be located, there’s a pretty good chance that we’ll soon be bringing your key people a chance to network with like-minded professionals from multiple industries, expand their knowledge, get answers to their questions, and explore how Zabbix can work for them.

Strategy 4: Provide adequate training

Equipping employees with the skills and knowledge they need to get the most out of a monitoring system means gaining a solid understanding of their current capabilities and then finding out which gaps you most urgently need to fill.
