# This plugin will graph the chassis temp sensors on a Dell PowerEdge Server
# via the omreport tool. It has been tested on the following chassis:
# 
#   PE2650/6650
#   PE2850/6850
#   PE2950
#
# To enable, link omreport_temps to this file. E.g.
#
#   ln -s /usr/share/node/node/plugins/omreport_temps /etc/munin/plugins/omreport_temps
#
# Configuration parameters for /etc/munin/plugin-conf.d/munin-node
#
# [omreport_*]
#   user 	 - User that has permissions to run the omreport binary
#   env.omreport - Path to the omreport binary
