-=head1 NAME
-
-hddtemp_smartctl - Plugin to monitor harddrive temperatures through
-SMART
-
-=head1 CONFIGURATION
-
-This plugin needs to run as root or some other user that has access to
-the harddrive devices.
-
-The following environment variables are used
-
- smartctl  - path to smartctl executable
- drives	   - List drives to monitor. E.g. "env.drives hda hdc".
- type_$dev - device type for one drive, e.g. "env.type_sda 3ware,0"
-             or more typically "env.type_sda ata" if sda is a SATA disk.
- args_$dev - additional arguments to smartctl for one drive,
-             e.g. "env.args_hda -v 194,10xCelsius".  Use this to make
-             the plugin use the --all or -a option if your disk will
-             not return its temperature when only the -A option is
-             used.
- dev_$dev  - monitoring device for one drive, e.g. twe0
-
-If the "smartctl" enviroment variable is not set the plugin will
-search your $PATH, /usr/bin, /usr/sbin, /usr/local/bin and
-/usr/local/sbin for a file called "smartctl", and use that.
-
-If the "drives" environment variable is not set, the plugin will
-attempt to search for drives to probe.

-=head1 NOTES
-
-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.
-
-Recent versions of the kernel driver use a separate major device
-number for monitoring purposes, like /dev/twe<n> or /dev/twa<n>. This
-can be put in the e.g. dev_sda environment variable, to allow the user
-to keep sda as the name of the disk.
-
-To avoid spinning up sleeping disks smartctl will use the --nocheck
-parameter. If this parameter isn't supported by your version of
-smartctl then hdparm will be used.  Note that hdparm isn't available
-on all platforms.
