Please note it's not duplicate of other questions where answer with
nethogs is accepted, since
nethogs isn't what I need.
I want to know how much each of my applications have eaten network traffic, on which interface, and when.
nethogs displays realtime traffic only. But I want to have the statistics: how much traffic each application used, hourly/daily/monthly/etc.
On Windows there are many such utilities, and they work literally out-of-the-box, but on Linux I can't find any.
Is there some utility like that?
