Yesterday, my server atuin (which is also serving this page) had some strange outtage. Packetloss at about 90%, even from the same rack (my boss has a server at the same hosting facility too, so I can test inhouse stuff ;)). About one hour later it was back. Without a reboot and without any interesting log-entries.
So I thought, I should setup some kind of monitoring: munin.
munin consists of two parts, a monitor and a node.
The node is a server, which you can gets stats from. The monitor is a small app which collects the stats from the servers and paints nice html.
The installation is quite easy.
Run the following on the server you want to monitor:
apt-get install munin-node
And this on the one which monitors:
apt-get install munin
Wait some minutes and http://monitor/munin/ should show some nice graphs. Yay!
I think I'll post some improved version of the ircu script tomorrow.
