Munin

I shall not start by repeating cliche apt-get install munin-node.

Important detailed disk statistics requires more then apt-get.

 wget http://somewhere/linux_diskstat_
 chmod a+x linux_diskstat_
 cp linux_diskstat_ /usr/share/munin/plugins/linux_diskstat_
 munin-node-configure --shell
 

The last command should return a lot of lines to cut&paste. Carefully select relevant lines. You probably want only local devices (ie. no iscsi and so on).

That's all!
