A timed alarm is a special-purpose threshold that enables you to track and respond to the absence of an event, rather than the occurrence of an event. For example, if your organization monitors for heartbeat events from a critical network resource, you can use a timed alarm to perform a user-defined action if a heartbeat event is not detected within the interval specified in the Time until Alarm Triggers field.
Each time the specified event is detected within the user-defined interval, the timer resets and the threshold monitoring begins again.
Timed alarm actions can be triggered by using event data substitution to reference the alarm ID text and by filtering on the event subtype defined in the Alarm Event Subtype field.
