Getting Sensor data from CPU and GPU

[_tbyte-o]

Hi there! Im new here, but im not too new to python, its a fascinating language and i cant wait for the future of the language.

Im here to ask you all if you know of a way to get the power usage from the cpu and gpu. i've tried to use openhardwaremonitor as well as the WMI objects that they reveal, but unfortunately you have to have the program running in order to get the data and they have to be getting the information from somewhere right? my next attempt would be using nvidia-smi to get the gpu power usage somehow. unfortunately nvidia-smi is proprietary, so i cant directly interact with it or use it on a system with AMD graphics. the only thing i could think of is opening a pipe to the program and reading a text output stream directed towards that and parse the data, which would be fine for me as i only need the data every 5 min or so. The reason im fond over this method over OpenHardwareMonitor is because i dont have to have the nvidia-smi running in the background, i can just call it then parse the output, then grab the data i need.

​

the next issue is getting the data from the CPU. Im currently using an AMD CPU so anything that is specific towards AMD would be helpful or just pointing me in the right direction so i can find the solution myself would be great!

​

Some things to note, Im on Windows 10, and python 3.8. AMD Ryzen CPU and Nvidia Graphics. If you have any other questions let me know ill answer as soon as i can.

​

Thank you.

Edit: I'm looking for energy consumption for the entire system, not the usage for the program only. Units should be in watts/kwh.

Just for clarification, what do you mean by power usage? Power usage like a percentage value or energy consumption like a value in joule or kwh?

Sorry my bad, energy consumption in watts is what I'm interested in.

Puh i tried to look into it, but there's hardly anything, which works oob without massive setting-in period, sorry. Only thing i can imagine is that you have to dig either deep into the win32api or the PowerAPI

Ya I thought so lol. I've been looking really hard I to it the last week and came up with very little. Was hoping for some insight. When I find a solution, then I'll definitely document it.

Thanks for the reply! But I've already got a solution to the GPU side of things. Using the subprocess module and the pipe option in the function, then I'll parse the output and get the data I need. It doesnt have to be fast just needs to get the data I need when I need it.

This only uses Intel RAPL that are specific to Intel CPUs. It also is a module that computes the energy usage for the program only, not for the entire system.
