i forget to mention how the plugins will work.

when gmond starts it will load all the monitoring plugins.. these plugins 
will register a part of the overall monitoring tree. 

the metric tree will be no different than say a filesystem directory 
structure.  i think we should "standardize" a part of the tree with the 
root being say "ganglia" but let the rest be free for other developers to 
do as they please.

ganglia
  + cpu
      + number
      + speed
      + user
      + system
      + nice
      + idle
  + load
      + 1 minute
      + 5 minute
      +15 minute
  + processes
      + ...
  + users
      + ...

.. just as an example.

<mu name="ganglia">
  <mu name="cpu">
    <metric name="number" value="..."/>
    ...
  </mu>
  <mu name="memory">
    ...
  </mu>
  ...
</mu>

at least in this part of the metric space we'll know where to expect 
things to be.
