One can always run xmlsysd instead, which is a very lightweight
on-demand information service. It costs you, basically, a socket, and
you can poll the nodes to get their current runstate every five seconds,
every thirty seconds, every minute, every five minutes. Pick a
granularity that drops its impact on a running computation to a level
you consider tolerable, while still providing you with node-level state
information when you need it.
Just a thought...;-)

I really have to look at this already. If the poll could be rigged so
that everyone gets polled at the same time, and it is not too frequent
(1/minute), this could be quite helpful. Especially if it doesn't have
to run a process/fork a thread to get state info. Ganglia is nice, but
it has some overhead. And occasionally gmond wanders off into a
different universe ...
If you have the pointer handy to the tool (save me a google, and get you
free advertising :) ) ...
