NAME

iostat - Munin plugin to monitor io-bound traffic (in blocks) on disks

APPLICABLE SYSTEMS

Linux systems.

CONFIGURATION

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.

USAGE

Link this plugin to @@CONFDIR@@/plugins/ and restart the munin-node.
