Using the JMX Administration API

The broker implements a comprehensive set of Java Management Extensions (JMX) MBeans that represent the broker's manageable resources. Using the JMX API, you can access these MBeans to perform broker configuration and monitoring operations programmatically from within a Java application.

In this way, the MBeans provide a Java application access to data values representing static or dynamic properties of a broker, connection, destination, or other resource. The application can also receive notifications of state changes or other significant events affecting the resource.

JMX-based administration provides dynamic, fine grained, programmatic access to the broker. You can use this kind of administration in a number of ways.

• You can include JMX code in your JMS client application to monitor application performance and, based on the results, to reconfigure the Message Queue resources you use to improve performance.

• You can write JMX client applications that monitor the broker to identify use patterns and performance problems, and you can use the JMX API to reconfigure the broker to optimize performance.

• You can write a JMX client application to automate regular maintenance tasks.

• You can write a JMX client application that constitutes your own version of the Command utility (imqcmd), and you can use it instead of imqcmd.

• You can use the standard Java Monitoring and Management Console (jconsole) that can provide access to the broker's MBeans.
