NBMonitor Network Bandwidth Monitor for Windows

NBMonitor tracks your internet bandwidth (upload and downloads) usage, monitors your entire Internet, it shows all the active connections you have to the Internet at any given moment and also the volume of traffic flowing through them. NBMonitor displays real-time details about your network connections and network adapter's bandwidth usage. Unlike others, it shows process names initiated network connections and allows you to set filters to capture only the traffic you are interested in.
