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.
Well, the folks I talked to at TACC were not enthusiastic about the amount
of resources ganglia uses. I will agree that there is a lot of unecessary
stuff that goes on, like converting everything to and from XML for each
message.

It's what I can remember in time to use.
