How to monitor http downloads and uploads?

[Meysam Mahfouzi]

Is there any easy way to monitor the amount of bytes sent and received on http port 80? I don't want to monitor the content of packets, just number and size of packets is important to me. Is TcpListener class suitable for this purpose? Any help would be greatly appreciated

You can user PerformanceCounter component by setting CategoryName property to Network Interface and after selecting appropriate counter.

Hi using api hooking you can monitor the network usage such: wsock32.dll has two funcaiton in the socket level 1 send 2 receive from that you can monitor and it works fine.and it calculates the entire upload download.
