|
||||
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.
