Measuring CPU usage from code

Hi,

I'm building a game server in Unity and I want to measure the % of CPU usage by the process in order to determine how many processes I can run simultaneously.
I want to to this via code, not the Unity profiler since I'm running it on a remote server.

I've searched the web but none of the stuff I've found worked for me. They all boil down to using
System.Diagnostics.PerformanceCounter like here:

But on my macbook pro the CPU usage returned is always 100%.

Any other ways? Thanks.

 

Maybe this answer can help you?

 

That is the same link that I posted. Which doesn't work for Unity.
