-While generally OK events close all problem events in Zabbix, there are cases when more detailed approach ​is needed. For example, when monitoring log files you may want to discover certain problems in a log file and close them individually rather than all together.+Event correlation allows to correlate ​problem events ​to their resolution ​in a manner that is very precise ​and flexible.
-This is the case with triggers that have //Multiple Problem ​Event Generation//​ enabled. Such triggers are normally used for log monitoring, trap processing, etc.+Event correlation can be defined: ​
-It is possible in Zabbix to relate problem events based on the event tags. Tags are used to extract values and create identification for problem events. Taking advantage of that, problems ​can also be closed individually based on matching tag. +  * [[:​manual/​config/​event_correlation/​trigger|on trigger level]] - one trigger may be used to relate separate ​problems ​to their solution 
- +  * [[:​manual/​config/​event_correlation/​global|globally]] ​problems ​can be correlated to their solution from a different ​trigger/polling method ​using global correlation rules
-In other words, the same trigger can create separate events identified by the event tag. Therefore problem events can be identified one-by-one and closed separately based on the identification by the event tag. +

-While correlation ​can be defined on the level of one trigger, it is also possible to relate separate triggers ​using global correlation rules.+
