As an operator of an umbrella monitoring system (which receives notifications from PRTG), I would like PRTG to only send a notification when a predefined amount of same sensors status changes happens in a predefined timeslot. E.g., there are ten of same sensor status changes of same sensortype of different devices in 10 mins which then results in one notification and not ten (for each sensor one notification). This could be useful in a library which holds a large number of same sensors which should not trigger a notification by its own, only if same event happens multiple times.
