Thanks Christian I'm trying to complete this dataset with CPU, RAM and other system metrics that could be interesting. Most of the tools gives you a whole view of the system or containers or pods.. is there any tool that could provides me the cpu consumption for an interval of time? I think I could assign this value to all the processes that wouldbe running at that moment. Thanks again
