You can configure the Non-Repetition Interval setting to prevent notifications from sending similar alerts, which are associated with the same condition, within a specified amount of time. The non-repetition interval is not applied for close sends.
Alerts will be sent for triggering events with a higher severity even if a prior alert has been sent for a triggering event of lower severity, and within the time-frame of the non-repetition interval.
The system determines when to resend the notification based on the time the last notification was sent, and not based on the start time of the triggering event. For example, if the event frame started at time t, and the service, after processing, sends the notification at time t1, the system uses t1 as the basis to calculate the time between alerts.
Note: If you specify both a resend interval and a non-repetition interval, the resend interval must be longer.
