#!@@PERL@@ -w
#
# Plugin to monitor harddrive temperatures through SMART.
#
# client-conf.d/-options:
#
# smartctl -- path to smartctl executable
# drives -- List drives to monitor. E.g. "env.drives hda hdc".
# type_$dev -- device type for one drive, e.g. "env.type_sda 3ware,0"
# args_$dev -- additional arguments to smartctl for one drive,
# e.g. "env.args_hda -v 194,10xCelsius"
#
# Note for users of RAID controllers (smartmontools currently only
# supports 3ware): you can specify the drives attached to your RAID
# controller(s) as raiddev_num (e.g. sda_0). Then you must specify the
# type like this: type_sda_0 3ware,0.
#
# $Log$
# Revision 1.1.2.5 2005/03/03 10:22:25 lupe
# Add feature to specify additional arguments to smartctl
#
# Revision 1.1.2.4 2005/02/17 10:59:33 lupe
# Support more than one drive on RAID controllers. Explain how to configure
# them.
#
# Revision 1.1.2.3 2005/01/29 22:14:36 jimmyo
# Make the plugin check all rdsks.
#
# Revision 1.1.2.2 2005/01/26 09:34:37 jimmyo
# Added license note.
#
# Revision 1.1.2.1 2005/01/25 21:00:05 jimmyo
# Added plugin generic/hddtemp_smartctl, made by Lupe Christoph. Made it the default hddtemp plugin.
#
# Revision 1.1 2004/11/10 16:11:27 jimmyo
# Added new plugin linux/hddtemp_smartctl, made by Peter Gervai (SF#1032727).
#
# Revision 1.0 2004/09/22
# New plugin: Peter Gervai <grin(*)grin.hu>
