Hi Al,
Can you show me some log that ipmi-sensors excutes 
on the matchine which support power/wattage?
I'm lack of matchine, and I want to known it looks like.
Thanks a lot.

Hi Easley,

For ipmi-sensors, you can run ipmi-sensors and see what sensors are
available.  For ipmi-oem, you'll have to look at the manpage and see if
your motherboard is supported.  Beyond that, you'll have to check with
the motherboard manufacturer or vendor.

IPMI does all its communication via the BMC, so it already does
everything via the BMC.

Remember, IPMI is a standard/interface that supports many system
management and monitoring functions.  However, there is no requirement
for a motherboard to support ALL the system management/monitoring
functions listed.  So if a motherboard supports power/wattage readings
via standard IPMI, FreeIPMI already supports it.
