System management interfaces

The brokers provide a service for independent system management agents.

This enables a central management facility to access information about any network that includes a WebSphere Message Broker broker domain.

This support ensures that existing system management agents can be extended to include WebSphere Message Broker resources.

WebSphere Message Broker brokers publish event messages, using fixed topics, in response to configuration changes, state changes, and user actions such as subscription registrations. WebSphere Message Broker also uses architected messages to publish events related to the status, and change in status, of the brokers. These messages are published using the reserved topic root $SYS in code page 1208.

An example of a fixed topic is:
$SYS/Broker/<brokerName>/Status/ExecutionGroup/<executionGroupName>
So the topic structure is fixed in this case, but obviously <brokerName> and <executionGroupName> are replaced with the appropriate values.
An example of the actual message data for this publication is:
<Broker uuid="12345678-1234-1234-1234-123456789012">
        <ExecutionGroup uuid="12345678-1234-1234-1234-123456789012">
                  <Stop>
                         <AllMessageFlows/>
                  </Stop>
        </ExecutionGroup>
</Broker>

A system management agent can subscribe to these topics, or to a subset of these topics, to receive the detailed information about activity and state changes in the WebSphere Message Broker broker domain.

The event messages have a fixed structure, defined in XML (Extensible Markup Language). The format of these messages, constructed in XML, is detailed in The XML message body. The messages cover configuration changes, state changes, error notifications, and detailed subscription and topic information (for example, a subscription registration).

You can develop or purchase system management adapters or customized administrative applications. These subscribe to the system management topics generated by WebSphere Message Broker to receive information on the broker domain activity.
