Re: [Freeipmi-users] The power consumption of computer

[Olaf Morgenstern]

Hi Easley,

we have some older Fujitsu servers where the BMC supports power supply wattage 
output. ipmi-sensors on a Fujitsu RX300 shows:

As you can see, sensor ID 384 is PSU power, but I'm in doubt if the sensor 
value is correct - it's only 60 Watts.

On a RX300S2, there is no sensor for PSU power. So we can't know the power 
wattage of this servers.

So, the simple rule is: ipmi-sensors scans all available sensors. If there is 
no sensor that shows the power wattage, then maybe ipmi-oem can provide a 
wattage (as Al said). If it doesn't, there is (actually) no way to get the 
power wattage with IPMI.

Regards,
Olaf
