# Home page is: http://smartmontools.sourceforge.net

# The file gives a list of devices to monitor using smartd, with one
# device per line. Text after a hash (#) is ignored, and you may use
# spaces and tabs for white space. You may use '\\' to continue lines.

# You can usually identify which hard disks are on your system by
# looking in /proc/ide and in /proc/scsi.

# The word DEVICESCAN will cause any remaining lines in this
# configuration file to be ignored: it tells smartd to scan for all
# ATA and SCSI devices.  DEVICESCAN may be followed by any of the
# Directives listed below, which will be applied to all devices that
# are found.  Most users should comment out DEVICESCAN and explicitly
# list the devices that they wish to monitor.

# Monitor SMART status, ATA Error Log, Self-test log, and track
# changes in all attributes except for attribute 194
# /dev/hdb -H -l error -l selftest -t -I 194

# A very silent check.  Only report SMART health status if it fails
