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 Event Broker broker domain.

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

WebSphere Event Broker brokers publish event messages, using fixed topics, in response to configuration changes, state changes, and user actions such as subscription registrations. WebSphere Event 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 Event Broker broker domain.

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