How do I get detail information from a service (e.g CPU_utilization)

Would you mind going about your solution in more detail and explain how that solves the issue? Maybe show an example? I just started using check-MK so I’m not sure what you mean by “CPU Utilization graphed as an item”.

I created a “State and count of processes”-rule, but then what? Applying the rule to the main folder doesn’t change the outcome of my GET-Request. Chances are of course, that I misconfigured something - so an example would be great.
