Hi Kaushal,

The atoptool web page clearly explains how atop, netatopd and the netatop kernel module interact. Have you even read the web page? Please read it first, and then ask a more specific question. Don't leave all the research work to other people.

I am referring to https://www.atoptool.nl/netatop.php and installed https://www.atoptool.nl/downloadnetatop.php kernel module netatop on CentOS Linux release 7.9.2009 (Core). How do I check Network activity per process? For example network activity for the Nginx webserver process.

#systemctl status netatop ● netatop.service - Netatop kernel module Loaded: loaded (/usr/lib/systemd/system/netatop.service; enabled; vendor preset: disabled) Active: active (exited) since Thu 2021-06-03 06:58:36 IST; 10min ago Docs: man:netatop(4) Main PID: 29083 (code=exited, status=0/SUCCESS) CGroup: /system.slice/netatop.service └─29086 /usr/sbin/netatopd

Please guide. Thanks in advance.
