This Ubuntu server is booted with CPU isolation isolcpus=0-7, so 8 cores from 16 are reserved and the only processes that use them are numbered as worker_0 - worker_7.
As can be see by top's per CPU utilization the usage IS measured properly for Cpu0 - Cpu7 so to take CPU6 & CPU7 as examples where they are only 18.9% & 35.7% idle respectively the relevant threads worker_6 & worker_7 just show 0.0% CPU usage.
I've tried updating top to the latest version, it didn't help... is this a known kernel bug maybe?

Could you edit your question and clarify what the problem is? I must be missing something, but I can't understand what you are asking.
– terdon♦

Please edit your question and add this. Tell us how you know the process is running and how you know it's currently using more than 0% CPU. How do you know it isn't waiting for input, for example, or just not running?
– terdon♦

@terdon, the problem is there is a process that is definitely using cpu, but it shows 0% in top's output. For example cpu 7 is clearly doing work from the top part of top's output and the ONLY process running on cpu 7 is worker_7 and yet it shows 0.0% cpu usage. Does that clear this up or should I still edit the question?

You should always edit your question to add more details. Comments are hard to read, easy to miss and can be deleted without warnings, so anything relevant should be added to the question where the next person can easily see it. Thanks!

Could you edit your question and clarify what the problem is? I must be missing something, but I can't understand what you are asking.

Please edit your question and add this. Tell us how you know the process is running and how you know it's currently using more than 0% CPU. How do you know it isn't waiting for input, for example, or just not running?

@terdon, the problem is there is a process that is definitely using cpu, but it shows 0% in top's output. For example cpu 7 is clearly doing work from the top part of top's output and the ONLY process running on cpu 7 is worker_7 and yet it shows 0.0% cpu usage. Does that clear this up or should I still edit the question?

You should always edit your question to add more details. Comments are hard to read, easy to miss and can be deleted without warnings, so anything relevant should be added to the question where the next person can easily see it. Thanks!
