There are several sensors in your demo (Voltages, temperature and fan speed)
How could you manage to create it????
We used lm-sensors on linux. Net-SNMP has bindings for it, and the information ends up in the HOST-MIB. You can snmpwalk hrSensorValue to see if you have anything being reported. Running lm-sensors by itself will also be useful to see if any problems are related to lm-sensors or net-snmp.

What Brady didn't know is that the Net-SNMP Red Hat provides includes a patch for LM-Sensors to work within Net-SNMP.
Maybe try lm-sensors' website and see if the patch is there; I'm not sure where else you could try after that.
You could also try to create a wrapper script around the 'sensors' program that you could run out of net-snmp's 'exec' setup.
