How to get plugin-container's cpu usage percent with python. This currently only handles one plugin container so your mileage may vary. You'll have to find your own cpu usage threshold if you actually want to use this to monitor if someone is actually watching a video or if it's just sitting still **further improvements:** You could use sh modul…
