I have an alert that triggers when the search returns 0 events for the last couple of hours and sends a slack message. It runs every 5 minutes on cron and looks a few hour back. However, for some reason that I don't know, the alert false triggers some times when it should not and when I manually do the search for which it triggered, I see a bunch of events during that time span. This happens once a month or so.
So if anyone know a solution for this or why this happens that would be great. If not, I'm thinking of changing the alert so that it only triggers if the result is 0 for 2 searches in a row (5 minutes in between) to avoid the false triggers. Is it possible to do this and how?
