Supported Agents Linux
Do not use this plugin. It will be removed soon. Use jolokia_metrics instead.

This checks uses the JSON HTTP service of j4p (from jmx4perl) to monitor the number of threads created by a Java application server like Tomcat or JBoss. You can define levels against the number of threads of the Java machine.

Take a look at the j4p_performance.mem manpage for instructions on how to set up the needed agent plugin.

Item

The instance name as configured in {j4p.conf} with the variable {instance}.

Discovery

One service is created for each JMX instance sent by the agent.
