As described in Overview of objects, TrueSight Middleware and Transaction Monitor (TMTM) monitors objects, and you can use any of the following methods to monitor them.
All of these methods work when the objects have been discovered or previously registered for monitoring. Once registered for monitoring, object attribute values (such as statistics, state, etc.) are published by the relevant TMTM extensions. These published values can be viewed and presented in a variety of views and dashboards.
Best practice
Object discovery, in combination with the policy action to register the object for monitoring, is the preferred method for the WebSphere MQ extension and its objects.
