Fixing Debian / Ubuntu iostat Munin Plugin
Munin is written in perl. Yummy.
I noticed that the iostat plugin was broken and was not returning any values. To fix this you need to change a line in the plugin code.
nano -w /usr/share/munin/plugins/iostat
You need to change line 176 to read:
next unless $tmpnam !~ \/c\d+d\d+$/
In nano, press ctrl + shift + – (or ctrl+underscore) and type 177 [enter]
That should do it!
