Re: [EXTERNAL] Restart apps based on total system CPU usage

[Mike D]

Hey Lutz,

The issue I have with checking the app itself is that it forks into many different children to perform the work so no single app is using all the CPU. What I want to check for is if the total system usage is BELOW a certain threshold, restart the parent app.

Thanks,

Mike

Hello Mike,
if the application is known you should look to the samples too.

Based on the following sample (from Configuration Samples)

you can define resource limits for each service.
