In my typical setup, I want a tool which will display download rates of a particular user/ subnet. I am configuring download limiting rules to user/ subnet but unfortunately have no tool to verify whether the config is working or not.

Manually checking output of iftop is helpful, but I would like to push the output to a file so that I could verify this at the end of the day. Getting it listed by ports is not a necessity. Traffic to and from will solve my purpose.

I would like the output of download rate of a user/ subnet to be written to a file for lets say a 5 second interval.
Please let me know if there is more information you require from my side. I am a newbie to linux and any input provided by you and the team will be highly appreciated. :)

iftop is designed to be a real time view of network traffic. I don't
think it's output would make much sense in a file.

Exactly what kind of report do you want to have generated?

Are you wanting to get a list of traffic to and from each address that
communicates with your system, broken down by port? Are you wanting
it to be divided into time intervals, or are you wanting totals?

You'd have to describe in much greater detail what it is you're
wanting to get from a file dump, and it's likely that there are better
tools out there already for what you're wanting.. ?
