#
# This plugin will graph the chassis fan speed on a Dell PowerEdge Server
# via the ipmi-sensors tool. It has been tested on the following chassis:
#
# PE1850
#
# To enable:
#
# ln -s /usr/share/munin/plugins/ipmi-fans /etc/munin/plugins/ipmi-fans
#
# Configuration parameters for /etc/munin/plugin-conf.d/munin-node
#
# [ipmi_fans]
# user - User that has permissions to run ipmi-sensors
# env.category sensors
#
# Parameters:
#
# config
# autoconf
#
# Author: Alexx Roche <munin-ipmi-plugin@alexx.net>
