Missing powersupplyclass metrics

[GioDoesntKnowCode]

Host operating system: 5.4.0-110-generic #124-Ubuntu SMP

node_exporter version: 1.3.1

Are you running node_exporter in Docker: Yes

Issue:

I am trying to get the metrics of the power supply class, and for some reason it isn't being exported. When I tried this on Windows it worked, and the log had 74 references when I CTRL+F "Power", but on Ubunut & Mac I only get 3.

What did you expect to see?

Power supply logs

What did you see instead?

Nothing

The log for ubuntu, and a screenshot of the working log on windows are below, it is the same version of node_exporter on both systems. I am not sure what is missing, I hope someone can assist me, Thanks in advance!

It's probably a kernel version thing, we just expose what we find in /sys/class/power_supply
