If you рave installed lm_sensors and you want to build graphics of cpu temperature or fan speed  you can do it with munin. all you need  it install munin (if it is not installed yet ..). Then you must "activate" senseors plugin check_sensors .
Simply create sym links :

#ln -s /usr/share/munin/plugins/sensors_   /etc/munin/plugins/sensors_fan 

#ln -s /usr/share/munin/plugins/sensors_   /etc/munin/plugins/sensors_temp

#ln -s /usr/share/munin/plugins/sensors_   /etc/munin/plugins/sensors_volt

for different linux distro path to sensors_ may be different !!!

you will have grapichs for fan speed, temperature and volt respectively.

don't forget restart munin-node, and after 5 minutes you will see first graphics

десь помітив в логах munin-а помилку, від плагіна ps_

Magic number checking on storable file failed at blib/lib/Storable.pm ...

пошук підказав, що це скоріш за все проблема версії бібілотек, що читали/писали файл (/var/lib/munin/plugin-state/iostat-ios.state), де зберігалася інформація потрібна для роботи того плагіну..

вирішив просто витер той файл і нехай плагін створить собі новий файл..

rm /var/lib/munin/plugin-state/iostat-ios.state
