I have a SHC 6.4.2 and when I try to use the log event alert action i have notice that if the index doesn't exist in the search head, the event is not generate.
Has anyone noticed that?
So if I am correct, is mandatory to define the same index in the shc to enable the functionality.
This sounds like you may not be forwarding all of the Search Head logs to the indexers. Search Heads should not be indexing anything locally in a distributed environment. See the following:
I didn't say that you need to store the alert in the search head... Is just a problem of the functionallity.
And sure that I am sending all the internal logs to indexers.
I open the question just to advise to the rest.
I tested this in a distributed environment and to get it to work i needed:
Forwarding in outputs.conf
defaultGroup = send2indexers
indexAndForward = false
Also the target index for the log event alert has to be defined on the searchheads.
Yeah. Had the same issue. In distributed environment alerts are written/indexed on SH, so index MUST exist there. But with index forwarding to an indexer, data will end up there at the end. Beware, index on SH and index on IDX must have the SAME name!
