I'm not too sure about this rule, as it's always evaluation for us, even though everything seems fine.

This still indicates a problem though. Its severity set to warning. We might also give a coefficient for the interval but I think we should have this.
With this alert, you can detect you have too many rules for a group for example. Or your queries take too much time.
It's not very critical but I still see value in this.
