triggers

Hosts, items, and triggers are some of the most basic concepts in Zabbix. To successfully configure their monitoring workflows, Zabbix users need to have a clear understanding of how these entities are used. This article is aimed at Zabbix beginners and should help anyone better understand the basics of Zabbix while providing guidance on how […]

Introduced in Zabbix 5.4, the new trigger expression syntax enables a problem detection logic that is more sophisticated and flexible than ever before. In addition to changing the syntax, the existing trigger functions have also been reworked. Many new functions have been added, redundant functions have been removed while existing functions have been improved to […]

There are many design choices to consider when we build our monitoring environment for high-frequency monitoring. How to minimize performance impact? What are the data retention policies with storage space in mind? What are the available out-of-the-box features to solve these potential problems? In this blog post, we will discuss when you should use preprocessing […]

Zabbix 5.4 has introduced a new unified syntax for trigger expressions and calculated items (including aggregate calculations). Discover what has changed and why the new syntax is better. Trigger expressions in Zabbix are used to define problem thresholds. An example of the old syntax: {<host>:<key>.<function>(<parameter>)}<operator><constant> Since Zabbix 5.4 the syntax of the trigger formula has […]

In earlier Zabbix versions, we had three categories of things we could manage inside the instance — triggers, calculated items, and aggregated items. Each of them had its own syntax, so we could not be sure what syntax to use in a certain case. That’s why we introduced the unified syntax for every category inside […]

A new set of trigger functions for long-term analysis of trend data will allow Zabbix to analyze historical data and generate alerts on detected anomalies.

User macros with context can be used to accomplish more flexible thresholds in trigger expressions. Different thresholds may be defined on user macro level and then used in trigger constants depending on the discovered context. In this post we are going to check simple example, how to configure it in real life scenario.

Zabbix trigger expressions provide an incredibly flexible way of defining problem conditions. If you can express your problem using plain English or any other human language, there is a great chance it could be represented using triggers. I’ve noticed that even experienced Zabbix users are not always aware of the true power of triggers. The […]

Often host level maintenance is too much. Picture a machine running multiple services: While one service has a scheduled downtime, others continue their work and you want to be alarmed about them. Zabbix has no maintenance on trigger level at present, but you can work around it quite easily.
