#!/bin/bash
#
# evaluate the current cpu usage of every vm running on this host
# separated by time spend in user mode and kernel mode
#
# Date: 2011-09-09
# Author: Gerald Schnabel ger@ldschnabel.de
#
# Usage: Place in /etc/munin/plugins (or link it there using ln -s)
#
# This plugin has to run with the same user like the VirtualBox Server rans
# Update munin plugin-conf.d/munin-node file with
# [virtualbox_*]
# user VIRTUAL_BOX_SERVER_USER
#
# Parameters understood:
#
# config (required)
# autoconf (optional - used by munin-config)
#
# Versions
# 2013-05-25 robi fix for handling vm names with dots and dashes; separate Kernel and User CPU graphs
# 2011-09-22 ger@ldschnabel.de fix for handling vm names with spaces and setup metric period to get values
# 2011-09-09 ger@ldschnabel.de initial version
