Java - JMX

For an application to be monitored using JMX the JMX Server should be running- com.sun.jmx.mbeanserver.JmxMBeanServer

To access the MBeanServer in the same JVM - ManagementFactory.getPlatformMBeanServer(); is the way to do it.

JMXConnectorFactory is for accessing remote MBeanServers (i.e. in a different JVM, and/or on a different host).

For an JVM instance to support JMX following needs to be passed to the VM
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false


Implemented using Java RMI

Java 6 allows for jconsole to attach itself to a running process even after it has been started without JMX incantations.
