Reduce notable events

[lucanzano]

Hello, we have created many custom correlation searches in our client's deployed instance. Right now they are creating too many notable events even with the "window limitation". Can somebody help?

Consider disabling less-useful correlation searches, especially information and low-priority events.  Re-enable them when the NE volume is under control

Tune the CSs so they only trigger when there is an event requiring attention.

Fix the problems that are triggering the NEs.

How do I do it?

Thank you for the answer

It depends on the searches.  Generally speaking, adjust thresholds within the search before triggering a notable event.  For example, instead of triggering when a single interesting event is found, trigger when 3 or more are found within some period of time.
