JMX (Java Management Extensions) Question:

WLS8 supports JMX but it uses weblogic implementation of JMX server. It does not supports generalise sun javax API which can be used with any JVM. There are some patches available which can be used with WLS8 which will enabled JMX based monitoring. Once JMX is enable there are many monitoring tools available in the market. One can even go for custom JMX utilities which can be used for server monitoring.
