I want a simple number in arbitrary units, but uniform in the sense that of any two workers the one with a higher metric is more probably to start lagging/drop frames/introduce artifacts/crash, simply put, demonstrate lack of sufficient CPU resources.
How do i pull or calculate such a number?
Thanks!
No magic. That’s your task 
We provide this:
https://mediasoup.org/documentation/v3/mediasoup/api/#worker-getResourceUsage
Don’t ask me please what those fields mean.
You also have the worker.pid and can use other NPM libs to get process resource usage given a PID.
stime and utime are clearly “sys” and “usr” time which https://linux.die.net/man/1/time would print for the worker process if it was to terminate at that point. which is good enough. thanks!
