Please install and configure lm-sensors (if not already done)

Edit /etc/omv-sensor.conf to fit your needs
and run '/usr/share/openmediavault/mkconf/collectd.d/sensors'
to create the rrd-scripts for OMV.

After that, please run '/etc/init.d/collectd restart'
to collect the values for your coretemp/fanspeed/HDDTemp. You can run 
'omv-mkgraph' to create the graphs.

After install, you can delete this folder

Have fun!
