When this tool came out a few months back, it was originally positioned as an add-on to OMEGAMON z/OS. As it turned out interest in the tool has been big enough that OMEGAMON JVM is now a stand-alone monitoring component.
Why worry about monitoring java on z/OS? Well, there might be more Java running on your z/OS environment than you realize. One of the nice out of the box features of OMEGAMON z/OS is that it will auto-discover all the Java activity on your system.
The example above shows the main panel for OMEGAMON JVM. The bottom portion of the panel shows all the JVMs that have been discovered on the system, but are not currently being actively monitored. The top portion shows JVMs where the OMEGAMON agent has been enabled, and in depth monitoring is happening.
You may be interested to find out just how much Java is, in fact, running on your system.
