Administrator Alarm Notifications

The ClusterCATS alarm notification feature provides instant feedback about critical events that take place within a cluster. Once an event triggers an alarm, ClusterCATS notifies one or more people by e-mail. The possible events that trigger an e-mail notification are listed below.

If an event you chose occurs, ClusterCATS sends an e-mail message to the designated person. The following table explains the notification schedule for each event.

Event type	Notification occurs...
HTTP Server Failure	Immediately
Server Busy Warning	Every 24 hours
Server Unreachable	Immediately
Web Server Failover	Immediately
ColdFusion Probe Failure	Immediately
