"jboss.mq:service=InvocationLayer,type=JVM" is irrelevant.
Look for "jboss.system=type=ServerInfo"
Yes , by using this query "jboss.system:type=ServerInfo" I am getting all memory info about JVM .
But again am not getting heap size of the JVM ??
And I want to know How many JVM runs when i start JBoss ?
Just one JVM.
I think the FreeMemory/TotalMemory refers to heap-size, anyways
