Description of problem:
Ideally, the 'n' switch of PCP atop should show the process-wise network bandwidth usage. As per the man page, PCP needs netatop named kernel module but this module is not well maintained and quite old so does not fit with current kernel (RHEL-8). Also, netatop is not maintained and supported by Red Hat so we can not really recommend customers to use it on the production system.
It has been said that it is possible for atop to read the 'ebpf' metrics and show the process-wise network bandwidth usage but this feature has to be added in PCP-atop.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. #pcp atop
2. use interactive command 'n'
It will not show the process-wise network bandwidth usage
PCP atop should show the process level network bandwidth usage.
