The Retrigger Filter acts as an event passthrough, which only generates an event if the input has not previously been triggered within the defined interval.
Typically, the Retrigger Filter would be applied at the end of a rule combination to avoid sending duplicate alarms. This provides more granular control than the Event Retrigger Time option. The events produced by the Retrigger Filter will have the event type of the inbound rule. When selecting this filter we have the options below:
•Name: Filter name.
•Can Trigger Events: Check this option if this rule can trigger events.
•Input: Input rule for this filter.
•Interval (milliseconds): Period in which the input event cannot generate another event.
•Event Actions: Desired event actions when this rule is triggered. To learn more about event actions see chapter How to configure event actions.
