We've been talking about this capability for a few years now :) Its 
called "dynamic metadata", we have some design around it and a grad 
student actually did some work in this area (its in the nagios branch in 
our public repo). Heiko has more info on the work that was done here. It 
wasn't ready for merging into master, but the concepts were prototyped 
and appeared to work.

Here's the wiki on the design:

In this way we could have a single generic MBean plugin that could discover all MBeans in a JVM and present the MBeans properties and operations as metrics and ops respectively. The admin could then choose which metrics to schedule.
