vmstat
Sadly there is no documentation for this plugin.
#!@@GOODSH@@
# -*- sh -*-
#
# Plugin to monitor the number of procs in io-sleep and other wait
# states. Uses `vmstat`.
#
# This plugin is now "legacy" because the generic processes plugin
# shows substantially the same information.
#
# Parameters:
#
# config (required)
# autoconf (optional - used by munin-config)
#
# Magick markers (optional):
#%# family=legacy
#%# capabilities=autoconf
OSV=`/sbin/sysctl -n kern.osrelease | cut -f1 -d.`
