There is no setting in JBoss AS that will give you this.

However, you have the jmx-console source and you could easily add that functionality to it (once you get over how ugly the code is - JSPs with embedded server-side script - yuck!).

But I have a question - are you concerned only with jmx-console access to mbeans? What if I used twiddle to invoke an mbean's method - would you want that monitored also? In that case, providing the functionality within jmx-console would not be sufficient - you would really have to add the monitoring to the JMX Server.
