The IBM IIB/ACE monitoring extension (QPWMB) provides status monitoring for brokers, execution groups, applications, libraries and message flows, as well as performance monitoring for execution groups, applications, libraries and message flows. The IBM IIB/ACE monitoring extension collects data from various WebSphere Message Broker properties and passes it to the MVMM Extensible Agent which, in turn, publishes it to the MVMM Topic Service and on to the Monitor Console.
