How to use item preprocessing regex to enrich trigger name?

[Gijs007]

I'd like to use the item preprocessing to capture a certain string from a eventlog.
How can I add this capture group to my trigger name?

Example:

task "updating application xyz"

. Should result in a trigger name that contains: task updating application xyz.

Regex:

task\s+"([^"]+)"

You cannot do it directly, as item preprocessing has nothing to do with the trigger or its name. Item preprocessing takes your check result and preprocesses it and stores the data what is a result of all that preprocessing...

Trigger name can use macros like {ITEM.VALUE} or {ITEM.LASTVALUE} which refer to the value(s) of the item(s) that is used in trigger expression... So first you need to construct a suitable trigger (based on your item values) and then you can use them...
