What’s New in Zabbix 4.2?
Here is a list of the most important functionality included into the new release:
- Official support of new platforms
In addition to existing official packages and appliances, Zabbix 4.2 now also caters to the following platforms: RaspberryPi, SUSE Enterprise Linux Server, Mac OS/X, MSI for Windows, Docker.
- Built-in support of Prometheus data collection
Now we offer an integration with the exporters using native support of PromQL language. Moreover, the use of dependent metrics gives us the ability to collect massive amounts of Prometheus metrics in a highly efficient way: we get all the data using a single HTTP call and then just reuse it for corresponding dependent metrics. Zabbix can also transform Prometheus data into JSON format, which can be used directly for low-level discovery.
- Efficient high-frequency monitoring
Quite often, high-frequency monitoring is overloading the monitoring system. We can avoid that with throttling for preprocessing, as it allows us to skip recurrent values. Now we can collect data with high frequency, instantly discover problems without keeping excessive amount of history data in the Zabbix database. Thanks to throttling with heartbeat we can have nice graphs as well.
- Validation of collected data and error handling
No one wants to collect incorrect data. With Zabbix 4.2 we can address that via built-in preprocessing rules that validate data by matching or not matching regular expression, using JSONPath or XMLPath. Now it is also possible to extract error messages from collected data. This can be especially handy if we get an error from external APIs.
- Processing millions of metrics per second
Prior to 4.2, all preprocessing was handled solely by the Zabbix server. Now we are ready to deliver greater scalability, since all preprocessing functions can also be performed by proxies. A combination of proxy-based preprocessing with throttling gives us the ability to perform high-frequency monitoring collecting millions of values per second without overloading the Zabbix Server.
