The boolean broker property imq.metrics.enabled controls whether such information is logged and the imq.metrics.interval property specifies how often metrics information is generated.
A logger component that writes out information to a number of output channels.

Support for the Java ES Monitoring Framework
A metrics message producer that sends JMS messages containing metrics information to topic destinations for consumption by JMS monitoring clients.
