By default the Message Queue metrics-message producing client is enabled to produce nonpersistent messages every sixty seconds. The messages are allowed to remain in their respective destinations for 5 minutes before being automatically deleted. To persist metrics messages, to change the interval at which they are produced, or to change their time-to-live interval, the administrator must set the following properties in the config.properties file: imq.metrics.topic.persist , imq.metrics.topic.interval, and imq.metrics.topic.timetolive .
In addition, the administrator might want to set access controls on the metrics destinations. This restricts access to sensitive metrics data and helps limit the impact of metrics subscriptions on overall performance. For more information about administrative tasks in enabling message-based monitoring and access control, see Configuring and Using Broker Logging in Sun Java System Message Queue 3.7 UR1 Administration Guide.
