I need something to give me traffic usage (in real-time) per process. I remember 'Online Armor' did something like this but that app is too bloated for my purposes.

I hope this isn't a dupe – I've seen questions about traffic monitoring (tools like Netlimiter, DU Meter were suggested) but I need something that will give me even more control.

There is Process Explorer

run it as administrative (you have to run it as administrative for the following "processor network" tab to appear) columns.."process network" Then click Receive bytes and Send bytes. Then sort by one of those columns e.g. Receive bytes. You can scroll right the right hand (window) pane, so you reach those 2 columns for bytes sent/received, and you still see process name as you see in the pic 'cos process name is in the left hand pane.

It shows a total rather than a rate.

the network doesn't appear – user299709 Dec 10 '14 at 5:09
@user299709 funnily enough I just got your symptom trying it now but I managed to correct it like this. Don't just run process explorer normally, Run As Administrator, then follow the instruction in my post i.e. to go to columns, I see a 'process network' tab and can choose send and receive. Let me know if that works for you – barlop Dec 10 '14 at 8:23
@barlop that did it! but seems like when i replace task manager, it still requires administrator privileges. – user299709 Dec 10 '14 at 8:28
@user299709 what do you mean when you say "when i replace task manager" ? – barlop Dec 10 '14 at 8:50

In Windows Vista/Windows 7:

  1. Start Task Manager (Ctrl+Shift+Escape)
  2. Go to the "Performance" tab
  3. Click "Resource Monitor" at the bottom of the pane
  4. Go to the "Network" tab

You should mention that this "Resource Monitor" feature is not an option in XP – barlop Jul 30 '11 at 13:08
Good point. Done! – RJFalconer Aug 1 '11 at 23:21
