The brokers provide a service for independent system management agents.
This service enables a central management facility to access information about a network that includes one or more brokers. Therefore, you can extend your existing system management agents to include IBM® Integration Bus resources.
Brokers publish event messages, using fixed topics, in response to configuration changes, state changes, and user actions such as subscription registrations. Brokers also use architected messages to publish events related to their operational status, and changes in that status. These messages are published using the reserved topic root $SYS in code page 1208.
$SYS/Broker/brokerName/Status/ExecutionGroup/integrationServerName
The
topic structure is fixed in this case, but obviously brokerName and
integrationServerName are replaced with the appropriate values.<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 IBM Integration Bus components.
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 applications subscribe to the system management topics generated by IBM Integration Bus to receive information about the activity of its resources.
