Configuring Forefront TMG alerts
Microsoft Forefront Threat Management Gateway events are generated by Forefront TMG services when particular run-time conditions occur. The alert service of Forefront TMG acts as a dispatcher and an event filter. It notifies you when specified events occur by triggering an alert for the event. Some events have additional conditions. In this case, both the event and the additional condition must occur before the alert is triggered.
Forefront TMG provides a number of predefined alerts for every type of event defined by Forefront TMG. The predefined alert definitions are summarized in Alert definitions.
