What really sets Zabbix apart is that every alarm condition or trigger (as it is known in this system) can be tied not only to a single measurement, but also to an arbitrary complex calculation based on all of the data available to the Zabbix server. Furthermore, just as triggers are independent from items, the actions that the server can take based on the trigger status are independent from the individual trigger, as you will see in the subsequent sections.
In this chapter, you will learn the following things about triggers and actions:
Creating complex, intelligent triggers
Minimizing the possibility of false positives
Setting up Zabbix to take automatic actions based on the trigger status
Relying on escalating actions
An efficient, correct, and comprehensive alerting configuration is a key to the success of a monitoring system. It's based on extensive...
