In this example, we want to raise the alert if we detect new active IP addresses that accept connections in the data center.
For detecting new active IP addresses, we will use the New server detected alert and will configure it to filter IP ranges belonging to Data Center subnets.

In this example, there is no specific example changes on this tab. Normally, however, you would use the three tabs (Users, Trap Recipients, and Compuware Open Servers) to specify where and how to send out alerts. If you specify nothing here, the alerts will be written only to the alert log.
The Review Summary screen of the alert definition wizard is displayed.
On the Review Summary page of the wizard, verify your alert settings before you apply them to the report servers.
