updation of /proc about the network traffic
 

Hi,

Could anybody elaborate on how exactly the network traffic information is updated in /proc/process_id directory. I could not find much in task_struct
about the network traffic.

Thanks for any help

You might find some useful information in this excerpt from the Absolute Bash-scripting Guide:

Hi,

Actually, in /proc, the information about the network traffic is updated but about the entire system , not on single process basis.. In task_struct , there are no links to the network information structures.. so how exactly can we know about the traffic generated by a process...

Thanks for any help

Then you'll have to do per-process accounting. Depending on logging purpose and application you could use some iptables rules ("owner" module?) or a traffic dissector.
