# smartctl -- path to smartctl executable
8
9
# drives -- List drives to monitor. E.g. "env.drives hda hdc".
9
10
# type_$dev -- device type for one drive, e.g. "env.type_sda 3ware,0"
12
13
# Use this to make the plugin use the --all or -a option
13
14
# if your disk will not return it's temperature when
14
15
# only the -A option is used.
16
# Note for users of RAID controllers (smartmontools currently only
17
# supports 3ware): you can specify the drives attached to your RAID
18
# controller(s) as raiddev_num (e.g. sda_0). Then you must specify the
19
# type like this: type_sda_0 3ware,0.

# Note for users of RAID controllers: you can specify the drives attached to
19
# your RAID controller(s) as raiddev_num (e.g. sda_0). Then you must specify
20
# the type like this: type_sda_0 3ware,0.
22
# For a cciss RAID controller use e.g.:
24
# env.type_cciss6 cciss,6
25
# env.dev_cciss6 cciss/c0d0
27
# Recent versions of the kernel driver use a separate major device number
28
# for monitoring purposes, like /dev/twe<n> or /dev/twa<n>. This can be
29
# put in the e.g. dev_sda environment variable, to allow the user to keep
30
# sda as the name of the disk.

# To avoid spinning up sleeping disks, you need the hdparm command in your PATH
