[CentOS] Power consumption monitoring

I have quite a few low-end development/test servers running
continuously and I would like to better manage their power
I have found interesting information on how to perform CPU scaling
(e.g. [1] or [2]).

But I cannot find if there is a way to (software) monitor power
consumption on CentOS (or other such data like CPU temperature, fan
speed etc.).

What I read so far is that support is quite limited in this kernel
(e.g. PowerTop not providing useful information).

Before I start tuning I would like to be able to measure whether my
changes are having any impact at all.

Thanks in advance,
