Question on Host Power Measurements

[keirafadams]

Hello!

I've been playing around with the pcm-power utility and the basic DRAM and per-socket power measurements make sense.

What I was wondering was if there was any way of getting "point-in-time" aggregate power draw for the entire host system, including things like attached PCIe devices (SSDs, GPUs, etc), or if PCM only measures Socket+Memory power draws.

If there is a way of doing so, could someone explain how to extract those metrics?

Thanks!
