hddtemp_smartctl - Plugin to monitor harddrive temperatures through SMART
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" environment 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.

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.
