You can configure the Resend Interval setting so that additional alerts are sent when the event frame has not been acknowledged or closed; it is a reminder that the event of interest leading to the notification is yet to be resolved. The resend interval specifies the time between sending successive alerts.
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.
