JMX agent not showing jvm data
Oracle WebLogic normally uses its own MBean Server which is separate from the Platform MBean Server and only provides remote access to its own MBean Server. As a
result, the JMX agent is unable to collect JVM data.
How to enable this:
Oracle WebLogic provides an option in the Domain -> General -> Advanced configuration page, which forces WebLogic to use the Platform MBean Server for its
own MBeans instead of a separate MBean Server. This option is turned on by default by WebLogic 10.3.3 and higher. Versions prior to 10.3.3 need to be changed. Enabling this option on allows the JMX agent to collect both WebLogic MBean data as well JVM data.
