There are several tools available that allow network traffic to be viewed graphically, but one of the most popular and widely used ones is Wireshark.
Wireshark is a free and open-source network protocol analyzer that enables you to capture and analyze network traffic in real-time. It allows you to see what's happening on your network at a microscopic level and provides detailed information about each packet that is being transmitted over the network.
One of the primary features of Wireshark is its ability to graphically display network traffic. You can view traffic in different ways, such as line graphs, bar charts, and pie charts. This allows you to quickly analyze network traffic trends and identify potential problems or security threats.
Wireshark also provides a variety of powerful filters that allow you to focus on specific types of network traffic, such as traffic originating from a specific IP address or traffic using a particular protocol. These filters allow you to quickly isolate and analyze specific network traffic patterns.
Overall, Wireshark is an essential tool for network administrators, security professionals, and anyone interested in understanding the inner workings of computer networks. Its powerful features and graphical interface make it easy to use, while its open-source nature ensures that it remains a popular choice for years to come.
