# Requirements :
#
# - ipmitool command line utility (and kernel drivers)
# - access rights to /dev/ipmi0 device (ie, root privileges
# can be configured in /etc/munin/plugin-conf.d/munin-node)
#
# Parameters supported:
#
# config
# autoconf
#
# Setup :
#
# ipmitool sdr || echo "please load IPMI kernel modules"
# cp ipmi_sdr_ /usr/share/munin/plugins/
# chmod +x /usr/share/munin/plugins/ipmi_sdr_
# ln -s /usr/share/munin/plugins/ipmi_sdr_ /etc/munin/plugins/ipmi_sdr_fan
# ln -s /usr/share/munin/plugins/ipmi_sdr_ /etc/munin/plugins/ipmi_sdr_current

# ln -s /usr/share/munin/plugins/ipmi_sdr_ /etc/munin/plugins/ipmi_sdr_temperature
# echo -e "\n[ipmi_sdr*]\nuser root\ntimeout 15\n" >> /etc/munin/plugin-conf.d/munin-node
