Monitor events in an alert

I want to monitor the amount of events for a period with a treshold.

How can I set this in an alert rule?

Hello @Lev2

Welcome to the Community!!

If you could share the usecase in more detail than as per that can provide proper suggestion.

Still for basic can use => "Index threshold rule" & set the conditions/actions as per your requirement.

Example :

Rule : With KQL filter
response : 503

Thanks!!
