WebSphere Message Broker event reports: general architecture

Brokers publish messages on reserved topics after significant events within the broker. By subscribing to these topics, a client can be informed when these events occur.

For each topic, the type of event and message body are explained. The body of these messages is in XML format.

An event publication can contain more than one entry if the topic is the same (for example, if several message flows are created in the same operation).

The general form of the system topics on which events are published is:
$SYS/Broker/broker_name/event_type/...
where:
broker_name
is the name of the broker issuing or raising this event.
event_type
is the type of the event and is one of:
  • Configuration
  • Neighbor
  • Subscription
  • Topic
  • Status
  • Expiry

This specification of topics helps clients to filter events, based on the broker from which the event originated and the type of event. The clients register subscriptions for these topics to receive the reports.

For specific events, additional information is included in the topic to help filter on the specific object that raised the event. The inclusion of the string Broker at the second level of the topic hierarchy allows for future extension to additional subsystems that publish system management events through the broker.
