Ok, you probably already have DataSources for some of these. You might try setting the jmx authentication credentials to see if they show up.

If they don't show up after that, you just need to build the DS. For that you'll need the mBeans for those metrics and define discovery and collection.

To tack on to this, if you need help figuring out what's available from the JVM, I personally use VisualVM to discover these mBeans -- setting up the JMX connection is fairly simple, and when you navigate to the beans, if you go to 'Metadata' tab, you should be able to introspect the appropriate JMX paths needed for the LogicMonitor DataSource DataPoints.

JMX is a protocol for communicating with java virtual machines, the Collector being one. What exactly are you asking? What are you trying to do?
