Ganglia collects metrics from hosts and trends them for the user.
Most of these metrics need to be collected from the host itself (CPU,
memory, load, etc.).

Besides, the footprint of Ganglia is very little.  I have yet heard of
a user complaining that Ganglia uses too much resources.  Of course,
YMMV if you need every last CPU/memory for your job, then you should
turn everything off at the cost of managing a blackbox.

Cheers,

Bernard
