Hi,
I have quite a few low-end development/test servers running continuously and I would like to better manage their power consumption. 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.).
Most machines simply don't have that hardware. Some laptops do and then, with proper kernel, you can run powertop (or read /proc/acpi/power...).
Some things are handled by motherboard and/or processor sensors and lm_sensors will access these sensors ("CPU temperature, fan speed etc.").
