Java virtual machine garbage collection
This check monitors the count and assumed time of the garbage collection. It
helps to recognize any deviation from the regular behaviour of the garbage
collection. Such deviations could be more garbage collection runs per
minute or an increase in the time the garbage collection is using per minute.
Since every tomcat instance has a different behaviour there are no default
values set to avoid false alarms.
To use this plugin, Jolokia and the agent plugin need to be installed
on the monitored server.
By default no levels are set because each virtual machine requires its own
The name of the application server instance and name of the garbage collection
as sent by the agent.
One check is created per garbage collector sent by the Jolokia agent.
