Fast Way to Upgrade Your Zabbix Knowledge

Post Syndicated from Nicole Makarova original https://blog.zabbix.com/fast-way-to-upgrade-your-zabbix-knowledge/20267/

Since Zabbix 6.0 LTS has been released with a lot of new features and improvements, it might be tricky for one to figure out how to use these features on their own. Here, Zabbix comes to the rescue with Upgrade Training Courses to boost your knowledge in just one day.

If you previously completed the Zabbix 5.0 core training, the Upgrade Program will be an excellent way to learn about the recent improvements and add-ons of the new version without retaking the entire course. It is akin to a crash course that saves you both time and effort.

Zabbix Upgrade Training Program Overview

The Upgrade Training Program consists of two courses: Zabbix 6.0 Certified Specialist Upgrade Course and Zabbix 6.0 Certified Professional Upgrade Course. Let us tell you more about each upgraded training.

The Certified Specialist Upgrade Course covers the updated and new features of the basics, such as different data collection approaches, problem detection, data preprocessing, different visualization features, and more. Some of the long-awaited features you will get familiar with during the upgrade course are new Dashboard Widgets (e.g.: Item Value Widget), Top Hosts Widget, and the ability to display your monitored infrastructure on the Geomap Widget. Another thing that might serve your interest is the Service Monitoring section, which has been completely redesigned with a focus on flexible business service monitoring, alerting, and root cause analysis.

On the contrary, Certified Professional Upgrade Course focuses on advanced environments, where infrastructure scalability and redundancy are the common requirements. Hence, this course includes six major features, with two of them being High Availability and Advanced Problem Detection. The Zabbix server High Availability feature allows you to deploy multiple Zabbix servers that will remain in standby mode and will be failed over if the currently active server becomes unavailable. The Advanced Problem Detection section focuses on anomaly detection and baseline monitoring features, as Zabbix now supports history functions. This means that Zabbix can semi-automatically detect anomalous values and create alerts if such values are detected. The same approach can be used in baseline monitoring: Zabbix can now calculate baseline values for your metrics and react if your values are outside of this baseline.

As you see, such extensive training wraps up all the meaningful recent improvements of Zabbix 6.0 and delivers them to you in one day, not requiring you to spend a week on the course retake. And besides, it is also cheaper than the entire course.

This is the first time Zabbix is providing a quick and easy way to upgrade existing Zabbix 5.0 Specialist and Zabbix 5.0 Professional certifications to Zabbix 6.0. The course is designed for experienced Zabbix administrators, who are working with Zabbix 5.0 on daily basis. The one-day course featuring all important changes and updates in the most recent Zabbix LTS version is a very cost and time-efficient option.

Applying for the Right Course

Now it is time to pick the right Upgrade Course to apply for if you are ready to evolve your Zabbix skills. Here are a few hints on how to do it.

If you have already completed our core training and received the Zabbix 5.0 Certified Specialist Certificate, you should apply for the Zabbix 6.0 Certified Specialist Upgrade Course. This one-day course includes 5 hours of training and a one-hour exam that will challenge you to check your knowledge of the whole Zabbix 6.0 LTS version and its new features.

Therefore, if you were certified as a 5.0 Certified Professional, go for the Zabbix 6.0 Certified Specialist + Professional Upgrade Course bundle. This one includes both: Specialist and Professional courses and lasts a little longer. After completing the Specialist course, Professionals will have their additional 1.5-hour training and a 30-minute exam to master their knowledge.

Useful Things to Know

We suggest revising your knowledge of the Zabbix usage, as the exam of the Upgrade Training Program includes questions about both: the entire Zabbix 6.0 LTS release, as well as new features and improvements. Feel free to use your Zabbix 5.0 materials from the previous core training you have completed or explore Zabbix Documentation in case the materials are unavailable to you for some reason.

Please, bear in mind that 6.0 Certified Professional Upgrade training is meant only for the 5.0 Certified Professionals who have previously acquired the 6.0 Certified Specialist level.

The Upgrade Training Program is available online all over the world in different languages and for various time zones. And what’s more, upon successful course completion, you will receive an official Zabbix training certificate stating you have upgraded to the Zabbix 6.0 Certified Specialist or Professional.

Ready for takeoff? Then check out the full schedule and cost of the program on our Upgrade Courses page and pick your training. For even more details, please contact our Sales Team.

Handy Tips #40: Simplify metric pattern matching by creating global regular expressions

Post Syndicated from Arturs Lontons original https://blog.zabbix.com/simplify-metric-pattern-matching-by-creating-global-regular-expressions/24225/

Streamline your data collection, problem detection and low-level discovery by defining global regular expressions. 

Pattern matching within unstructured data is mostly done by using regular expressions. Defining a regular expression can be a lengthy task, that can be simplified by predefining a set of regular expressions which can be quickly referenced down the line.  

Simplify pattern matching by defining global regular expressions:

  • Reference global regular expressions in log monitoring and snmp trap items
  • Simplify pattern matching in trigger functions and calculated items
  • Global regular expressions can be referenced in low-level discovery filters
  •  Combine multiple subexpressions into a single global regular expression
Check out the video to learn how to define and use global regular expressions.
Define and use global regular expressions: 
  1. Navigate to Administration → General → Regular expressions
  2. Type in your global regular expression name
  3. Select the regular expression type and provide subexpressions
  4. Press Add and provide multiple subexpressions
  5. Navigate to the Test tab and enter the test string
  6. Click on Test expressions and observe the result
  7. Press Add to save and add the global regular expression
  8. Navigate to Configuration → Hosts
  9. Find the host on which you will test the global regular expression
  10. Click on either the Items, Triggers or Discovery button to open the corresponding section
  11. Find your item, trigger or LLD rule and open it
  12. Insert the global regular expression
  13. Use the @ symbol to reference a global regular expression by its name
  14. Update the element to save the changes
Tips and best practices
  • Each subexpressions and the total combined result can be tested in Zabbix frontend 
  • Zabbix uses AND logic if several subexpressions are defined 
  • Global regular expressions can be referenced by referring to their name, prefixed with the @ symbol 
  • Zabbix documentation contains the list of locations supporting the usage of global regular expression. 

Sign up for the official Zabbix Certified Specialist course and learn how to optimize your data collection, enrich your alerts with useful information, and minimize the amount of noise and false alarms. During the course, you will perform a variety of practical tasks under the guidance of a Zabbix certified trainer, where you will get the chance to discuss how the current use cases apply to your own unique infrastructure.

  • AWS, Azure, Google Cloud, Digital Ocean, Linode, Oracle Cloud, Red Hat OpenShift

Upgrading to Zabbix 6.2

In order to upgrade to Zabbix 6.2, you need to upgrade your repository package and download and install the new Zabbix component packages (Zabbix server, proxy, frontend, and other Zabbix components). When you start the Zabbix Server, an automatic database schema upgrade will be performed. Zabbix agents are backward compatible; therefore, it is not required to install the new agent versions. You can do it at a later time if needed.

If you’re using the official Docker container images – simply deploy a new set of containers for your Zabbix components. Once the Zabbix server container connects to the backend database, the database upgrade will be performed automatically.

You can find step-by-step instructions for the upgrade process to Zabbix 6.2 in the Zabbix documentation.
