Nvidia-smi does not show power usage

I have an Optimus setup, I want to figure out the power consumption when using the Intel and when running an app with the nvidia GPU…but sadly, when I run nvidia-smi, power consuption is N/A.

Is there anyway I can measure the power consumption ?


To use Nividia “on demand” look at this page (it wrote it) : https://doc.ubuntu-fr.org/asus-a17-tuf766iu
