When I run a query using stats count , I can see Events count as "636 events (4/26/18 8:00:00.000 AM to 5/3/18 8:32:45.000 AM)"
but when i open the Events tab , it shows Your search did not return any events because you are in Fast Mode. Search in Verbose Mode to see the events. The same message displays for Smart mode as well.
and in all the 3 modes , Statistics count is zero.
In this case , an scheduled email alert for the query , wouldn't be triggered because Statistics count is zero? Is this correct?
Whenever you use stats (or chart or timechart or ... or xyseries, etc.), your UI moves to the stats tab which means that the alert will also use that tab. So if your alert condition is Number of events > 0, it means on the stats tab. So the behavior is correct.
It would depend upon the alert condition you've set while setting up the alert. If your alert conditions says "if number of result is greater than 0", then if stats count is zero, no alert will be fired.
The event count below the search bar shows the event count matched your search criteria, before aggregation. The count on "Statistics" tab would show the actual result returned by your full search. The alert condition uses the result count not the event count.
Yes, it's correct. 🙂
When for example your initial query contains results, but you're doing a | stats by somefield, and that somefield doesn't exist in any those events, you get 0 results. An alert that aims for more than 0 results would therefore not fire.
Hope that helps - if it does I'd be happy if you would upvote/accept this answer, so others could profit from it. 🙂
