#
# Plugin to monitor hard drive temperatures.
#
# This plugin is an alternative to the hddtemp_smartctl, which is the
# preferred one.
#
# Requirements:
# - S.M.A.R.T. to be turned on for your hard drives
# - hddtemp program installed and in path
#
# Parameters supported:
#
# config
# autoconf
#
# Configurable variables
#
# hddtemp - Override default program
# ignore - Disks will not be touched
# "/dev/sdX /dev/sdY /dev/hdZ"
