Process level networking stats.

Process level networking stats.

[Ben Greear]

Hello,

I am interested in a relatively straight-forward way to know the tx/rx bytes
sent/received by a process.  I do not want to play tricks with packet capture,
and I want this to work for some arbitrary process like a web browser.

I wasn't able to find anything existing for this, though perhaps it exists
and I didn't find it.

If anyone has pointers to existing work in this area, please let me know.

And if not, then any suggestions for best way to go about implementing
this?  I assume I should start poking in net/socket.c, and perhaps directly
into ipv4, ipv6 socket logic with care not to count anything going over
localhost??

Thanks,
Ben

What is "relatively straight-forward"? :)
You could out the process in a cgroup and use cgroup hooks

The main thing is that I don't want to try to do it with packet capture.
Thanks for the suggestion of using cgroups.  I will look into that.

Thanks,
