Network Monitoring devices for bandwidth tracking

Question

I'm looking for preferably a device, but I'll settle for an application. I'd like to get an idea of what is out there. Something just to get a total count from what computer, And maybe by common ports.

I'm not looking for a detailed reporting like wireshark, unless wireshark can do summaries and be running for a whole month without issues.

Essentially, I just want an idea of where my monthly bandwidth is going and by what computers / devices. Ie computer A does a lot of website traffic, computer B gets a lot of steam downloads, device C has got some virus setting out on an unknown port. Now to be clear, I would only know that Device C has some virus on it as the logs would show either lots of bandwidth on a unknown port which then gets be to investigate.

Being able to ignore / filter any traffic that stays behind the router would be nice. This computer as of this post has over a gig of traffic, but mostly to the networked drive I have, I'm really only interested in what uses internet bandwidth, and who's using it... and if possible, what it is.

Answer 1

If you ask for some tools,maybe google/superuser is better for you.

If you ask how to program, you can use Raw Socket .

RawSocket is able to work as network sniffer. So you can get your networking bandwidth using.
