Local Network Monitor

Local Network Monitor is an application that lets you monitor and control network activity of TCP/IP protocol stack on your local system in a real-time. It monitors activity at the Transport Driver Interface (TDI) level of networking operations in the operating system kernel and intended for tracking down network-related configuration problems and analyzing application network troubleshooting, investigating and blocking suspicious network activity. Local Network Monitor lets you obtain detailed statistics on the application network requests and amount of data sent and received over a connection and view the packet’s content, which makes it a useful tool for performance diagnostics.
