# Munin plugin for MegaRAID
# This plugin can graph:- Currently Drive Temperature and Error Count
#
#---------------------
# Examples
# Create a symbolic link to MegaRaid_<AdapterNumber>_<temp|media|other|predictive>
# ln -s /usr/share/munin/plugins/MegaRaid_ /etc/munin/plugins/MegaRaid_0_temp
# graph temperature on adapter 0
#
# ln -s /usr/share/munin/plugins/MegaRaid_ /etc/munin/plugins/MegaRaid_0_error
# graph media errors on adapter 0
#
# ln -s /usr/share/munin/plugins/MegaRaid_ /etc/munin/plugins/MegaRaid_1_temp
# graph temperature on adapter 1
#
#---------------------
