Debian: Munin - S.M.A.R.T.

apt-get install smartmontools

SMART muss nun für jede Festplatte, die überwacht werden soll, aktiviert werden. Das geschieht mit dem Schalter -s on:

smartctl -s on /dev/sda

Ein erster Test mit…

smartctl -a /dev/sda

… sollte eine solche oder ähnliche Ausgabe erzeugen

Die smartmontools verfügen über einen Daemon, der in definierbaren Intervallen die Festplatten prüfen kann. Um den zu aktivieren, ist /etc/default/smartmontools anzupassen.

/etc/init.d/smartmontools start

Bei dem smart_-Plugin handelt es sich um ein sogenanntes Wildcard-Plugin. Das heisst, dass die zu überwachenden Festplatte als Variable nach dem Unterstrich angegeben wird.

ln -s /usr/share/munin/plugins/smart_ /etc/munin/plugins/smart_sda
ln -s /usr/share/munin/plugins/hddtemp_smartctl /etc/munin/plugins/hddtemp_smartctl

/etc/munin/plugin-conf.d ist noch anzupassen:

[hddtemp_smartctl]
user root
group disk
env.drives sda

[smart_*]
user root
group disk
env.smartpath /usr/sbin/smartctl

/etc/init.d/munin-node restart

Fertig.
