## ESME supports JMX

1. To enable JMX, you must activate it in your default.props file:
_jmx.enable=true_ \- default is false.
1. Connect to ESME with your normal JMX-enabled tool. For example, [JConsole](http://java.sun.com/j2se/1.5.0/docs/guide/management/jconsole.html)

The following picture shows JConsole monitoring ESME running in a Tomcat
(6) instance.
