Clustered view of jmx-console

I am running 3 jboss instances on different PCs in a cluster successfully. However, I want to get a consolidated view of all the custom MBeans that I am running on the 3 PCs. Is there a way that I can do this using the build-in jmx-console on any one of the PCs?

Each jmx-console reports only what is available in its own server. However, since the jmx-console works by querying the MBean Server, which it obtains via JNDI, you might be able to easily modify the jmx-console code to do what you want.

The only other thing I can think of is if you know what data you are interesting in consolidating, you could write a script that makes use of the twiddle command to gather the data. This is essentially what is done with Nagios and GroundWork Monitor.

what is a twiddle command exactly?
Thanks for the reply BTW. This is exactly what I thought it would be. I will try to modify the jmx-console code. I went thru it once and it is very easy to understand

I also had another idea. If I make my MBeans as singletons, then can I view them from all the JBoss instances in the cluster?

Documentation on twiddle can be found at http://docs.jboss.com/jbossas/guides/j2eeguide/r2/en/html_single/#d0e2252.

You have read the JBoss documentation, have you not? It contains an entire chapter on the JMX implementation in JBoss.
