Mule - Default Jmx Agent

One can configure several JMX agents simultaneously using the <jmx-default-config> element. When set, this element registers the following agents:

• JMX agent
• RMI registry agent (if necessary) on rmi://localhost:1099
• Remote JMX access on service:jmx:rmi:///jndi/rmi://localhost:1099/server
• (Optional) Log4J JMX agent, which exposes the configuration of the Log4J instance used by Mule for JMX management
• JMX notification agent used to receive server notifications using JMX notifications
• (Optional) MX4J adapter, which provides web-based JMX management, statistics, and configuration viewing of a Mule instance

When this change is included, mule-config.xml would look like the following.

mule-config.xml

</mule>

With this configuration, when the server gets started, we should see the following message in the console.

Now the Mule Mbeans can be accessed using JConsole and individual services can be started or stopped easily. Jconsole comes with JDK 1.6 by default.
