Memory usage of a JVM

Distribution: official part of Check_MK
License: GPL
Supported Agents: Linux

This check allows to monitor the usage of heap and non-heap memory area usage on web application servers.

To use this plugin, Jolokia and the agent plugin need to be installed on the monitored server. It will then fetch the memory usage from the JMX status info of the remote Java Virtual Machine.

The check can alert if the WARN/CRIT thresholds for a configurable heap, nonheap or total is exceeded.

Item

The name of the application server instance as configured by the agent.

Discovery

One check is created for each Jolokia instance sent by the agent.
