Then install SMARTMonTools via aptitude like this:

sudo aptitude install smartmontools

A simple check of SMART status from the command line.

Check the SMART status of /dev/sda:

sudo smartctl -i /dev/sda

Output would be something like this; note this device doesn’t have SMART capability but the report format is similar for SMART capable devices:

smartctl 5.41 2011-06-09 r3365 [x86_64-linux-3.13.0-63-generic] (local build)

SMART support is: Unavailable - device lacks SMART capability.

Enable the SMARTMonTools daemon (smartd) on startup.

First open up the smartmontools daemon config file:

sudo nano /etc/default/smartmontools

And uncomment the line that reads start_smartd=yes:

# uncomment to start smartd on system startup

Adding a device to the smartd.conf file for monitoring.

First open up the smartmontools config file:

sudo nano /etc/smartd.conf

And add some monitoring configs like this to the bottom; note only one is active and the other is commented out as an example:

# 2015-09-24: Example config.
#/dev/sda -a -d sat -I 194 -m -M test -s (S/../.././02|L/../../6/03)
# /dev/sda -a -d ata -I 194 -m -M test -s (S/../.././02|L/../../6/03)
/dev/sda1 -a -d ata -I 194 -m -M test -s (S/../.././02|L/../../6/03)

Adding to the smartd.conf file to Munin.

Create a symbolic link for the plugin to be active:

sudo ln -s /usr/share/munin/plugins/smart_ /etc/munin/plugins/smart_hda

Check the config:

sudo nano /etc/munin/plugin-conf.d/munin-node

Check to see if [smart_*] entry exists. If it doesn’t just add this simple config to bottom of the file:

user root

Sample contents from the smartd.conf for reference.

# Sample configuration file for smartd.  See man smartd.conf.

# Home page is:

# smartd will re-read the configuration file if it receives a HUP
# signal

# 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.
#DEVICESCAN -d removable -n standby -m root -M exec /usr/share/smartmontools/smartd-runner

# Alternative setting to ignore temperature and power-on hours reports
# in syslog.
#DEVICESCAN -I 194 -I 231 -I 9

# Alternative setting to report more useful raw temperature in syslog.
#DEVICESCAN -R 194 -R 231 -I 9

# Alternative setting to report raw temperature changes >= 5 Celsius
# and min/max temperatures.
#DEVICESCAN -I 194 -I 231 -I 9 -W 5

# First (primary) ATA/IDE hard disk.  Monitor all attributes, enable
# automatic online data collection, automatic Attribute autosave, and
# start a short self-test every day between 2-3am, and a long self test
# Saturdays between 3-4am.
#/dev/hda -a -o on -S on -s (S/../.././02|L/../../6/03)

# 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

# Monitor all attributes except normalized Temperature (usually 194),
# but track Temperature changes >= 4 Celsius, report Temperatures
# >= 45 Celsius and changes in Raw value of Reallocated_Sector_Ct (5).
# Send mail on SMART failures or when Temperature is >= 55 Celsius.

# An ATA disk may appear as a SCSI device to the OS. If a SCSI to

# this can be flagged with the '-d sat' option. This situation may
