Link Monitor

You use link monitors to verify the efficient routing of test messages. These messages are called ping messages. At every polling interval, a ping message is sent to every server and system configured in the monitor.

When you set up a link monitor, you can specify a nonexistent recipient on the target system. The link monitor determines if the link is active by sending a message to this recipient and waiting for a non-delivery report (NDR) from the server.

Note   If a target custom recipient matches the link monitor's requested nonexistent custom recipient, the link monitor fails to receive an NDR and reports that the link is unavailable.
