Sys-mon is a lightweight, containerized system monitor written in python that can be used on all versions of linux.
I was using a similar system monitor program that ran as a service to output performance stats to Home Assistant. For a while it worked but it was only able to run on debian based systems. I decided to make a similar prgram but running in docker so it could run across different types of linux distros.
Run the provided docker-compose.yaml with docker compose up -d and docker should pull the correct image.
