Net Activity Diagram is an application for monitoring network and Internet activity on a computer. The application allows you to monitor all established connections, display various warning messages, and analyze traffic for specific periods of time. Current network activity can be displayed both in a separate window and in the taskbar (transparency, colors and font of the informer can be configured). In addition, Net Activity Diagram allows you to monitor network traffic independently for each port, providing the ability to monitor each type of traffic separately (web traffic, FTP traffic, media coverage traffic, etc.). The flexible notification system of the program can inform the user in case of exceeding the established traffic limits. There is a built-in Wi-Fi signal status indicator.
