IFPCAlert::EventsBeforeRaise property

Applies to: desktop apps only

The EventsBeforeRaise property gets or sets the minimal number of occurrences of the event for which the alert is issued before the alert can be issued.

The MinutesBeforeReRaise, EventsBeforeRaise, and MinEventsPerSecond properties set the three thresholds that the Microsoft Firewall service uses to issue alerts. For each alert, the Firewall service stores the time when the event last occurred, a count of how many times the event has occurred per second, and a count of the total number of times that the event has occurred. An alert is issued, and the alert invokes the actions defined for it only when the three threshold requirements for issuing the alert are met simultaneously.

The EventsBeforeRaise property sets the threshold number of occurrences of the event.

This property is read/write.
