“In this article I will describe how you can monitor multiple
systems with munin. munin produces nifty little graphics about
nearly every aspect of your server (load average, memory usage, CPU
usage, MySQL throughput, eth0 traffic, etc.) without much
configuration. I will install the munin client on all systems that
are to be monitored (including the munin server itself); the munin
clients will then report to the munin server.“This tutorial was written for Debian Etch, but the
configuration should apply to other distributions with little
changes as well…”
