Message monitoring

Message monitoring is the process of identifying the route a message has taken through a queue manager network. As a message passes through a queue manager network, various processes perform activities on behalf of the message. By identifying the types of activities, and the sequence of activities performed on behalf of a message, the message route can be determined.

The following techniques are available for determining a message route:

• The WebSphere MQ display route application (dspmqrte), see WebSphere MQ display route application.

• Trace-route messaging, see Trace-route messaging.

• Activity recording, see Activity recording.

These techniques all generate special messages that contain information about the activities performed on the message as it passed through a queue manager network. The information returned in these special messages can be used to do the following:

• Record message activity.

• Determine the last known location of a message.

• Detect routing problems in your queue manager network.

• Assist in determining the causes of routing problems in your queue manager network.

• Confirm that your queue manager network is running correctly.

• Familiarize yourself with the running of your queue manager network.
