#
# Munin plugin to monitor hdd temperature from a hddtemp daemon.
#
# This plugin is an alternative to the hddtemp_smartctl, which is the
# preferred one.
#
# Author: Stein Magnus Jodal <jodal at users.sourceforge.net>
#
# Depends on `hddtemp` <http://coredump.free.fr/linux/hddtemp.php> by
# Emmanuel Varagnat <coredump@free.fr> running as a daemon.
#
# If fetching temp from another machine, remember to bind hddtempd to the right
# interface. Loopback only is default.
#
# Parameters understood:
#
# host - Change which host to graph (default localhost)
# port - Change which port to connect to (default 7634)
# scale - C for Celsius, F for Farenheit (default C)
#
# This plugin is based on the apt plugin.
#
#
# Usage: place in /etc/munin/node.d/ (or link it there using ln -s)
#
# Parameters understood:
# config (required)
# autoconf (optional - used by munin-config)
#
#
# v1.2 2004-06-07
# - Renamed to hddtempd
# - Now more generic, not only localhost
# v1.1 2004-05-23
# - Fixed support for multiple disks
# v1.0 2004-05-17
# - Initial version
#
#
# Magic markers - optional - used by installation scripts and
# munin-config:
