Traffic monitor

Question

Hi.
Is there any software that will allow me to see what exactly software how much exactly megabytes have downloaded from the internet?
Something like list of all active connections by applications, so I can inspect WHO eating traffic.
Thanks!

Most of the options you'll find will count traffic in and out your machine. However, that's not necessarily going to tell you what you want.
For example, will it separate internet traffic vs. local traffic (e.g. that 50-page report you print counts as megabits in and out of your machine, but never touches your ISP link).
Then, at the next level, it's very hard to map the traffic to specific applications.
It's easier (but not 'easy') to map to a particular type - e.g. port 80 traffic is web traffic - but not to a particular app (e.g. FireFox vs. Safari).
The best place to see your internet volume is at your router - most routers have some support for port statistics - but that won't give any per-port or per-application stats.
So, what you're asking for (application-specific stats) is really hard to achieve.
