iostat - Munin plugin to monitor io-bound traffic (in blocks) on disks
The plugin detects block devices from /proc/diskstat or /proc/stat. By default it will only show un-numbered devices such as sda and not sda0. By setting
[iostat] env.SHOW_NUMBERED 1
it will show numbered devices. This is sometimes needed in virtualized environments (e.g. Xen) where sda1 to sda<n> exists but not sda. In a virtualized environment this is usefull to show which guest OS/dom-U IO-traffic originates in.
Link this plugin to @@CONFDIR@@/plugins/ and restart the munin-node.

This plugin has been in Munin since it was called "LRRD". The log for this file shows that there was a rewrite by Mike Fedyk applied in January 2004. We have no other records of who wrote it.
