Q. We have some Java applications that expose monitoring information via JMX (Java Management Extensions). Is there a probe that I can use to monitor the JMX agent?

A. You can use the Nagios Plugin probe to invoke the Nagios "check_jmx" plugin. InterMapper invokes the plugin and uses the exit value to set the condition of the device. It uses the performance data returned by the plugin to create a nice display of chartable data. If the "check_jmx" plugin does not provide all the functionality that you need, you can use the plugin as a template to create a customized Nagios plugin that uses JMX to do exactly what you want.
