[PDF] Real-time network traffic monitoring and analysis are two core works to most enterprise network administrators. However, most administrators soon give up on network monitoring.  This is because they find collecting network traffic complicated.  Even if they manage to capture network conversations they find it challenging to analyze the raw data in a meaningful way. In this article, you will read how to monitor and analyze real-time network traffic by the great network monitoring software– AthTek NetWalk. If you have no idea about this software, please download and install the free personal edition for a quick view.


When you open AthTek NetWalk for the first time, you will be asked to choose an internet adapter of your network. You can also switch to another one in program’s toolbar. After then the real-time network traffic will be displayed in some dynamic diagrams in AthTek NetWalk. Acquiescently you will see some raw data in real-time such as top hosts and bandwidth utilization. You can customize these real-time dynamic diagrams as you need. If you don’t need to do further troubleshooting, these dynamic diagrams could be a network analytic report for real-time network monitoring.
