You need to enable JMX by adding the following JVM arguments :

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false

-Dcom.sun.management.jmxremote.ssl=false

These parameters will allow any JMX monitoring tool to access and monitoring your application.

Also i suggest you to use visualVM its more powerful tool. some features for visualVM:

• Provide a CPU profiling.
• Provide all info about Threads.
• Provide the JVM Heap and the memory states.
• Provide Info about the GC activities.
