When running pcm as a docker container in a linux system of Model name: Intel(R) Core(TM) i5-10210U CPU @ 1.60GHz. Getting below errors even when i run it as a root. Used https://github.com/intel/pcm/blob/master/doc/DOCKER_README.md as reference.
Where as installing sudo apt install pcm and direct pcm command is running fine without issue. I want to use grafana output for monitoring.

Hi Thomas,
I have tried both privilaged commands and command with limited capabilities without privilaged both leading to same error. Is there any other flags which should be set ?
No. I am not using. I do not see any tools using performance monitoring counters running.
