Correlation in Zabbix can be used on two different levels:

- On Global level
Trigger level-based correlation: As the name suggests, this occurs on triggers and can be used to relate different problems to a solution by closing, for example, a trigger. Trigger-based event correlation, in short, allows us to correlate separate problems reported by one trigger. It's very useful for log-monitoring, SNMP traps, and so on. In Chapter 10, Advanced Item Monitoring, we will see how we can use trigger-based correlation in our log monitoring to close triggers based on tags.
Global-based correlation: This is a way to correlate problems to a solution based on different triggers by making use of global rules. ...
