How to monitor network traffic in windows 7 with Capsa network analyzer?

Network traffic is data in a network. In computer networks, the data is encapsulated in packets. So network traffic monitoring is to capture all the packets going down the network. Sometimes, it will be very useful to check your network activity. When Windows 7 network is very slow, internet browsing is very slow, connection problems and high network activity occurs when you do nothing, you will find this really helpful. The purpose of this article is to help you understand how to monitor network traffic in windows 7 with Capsa network analyzer.

About Capsa Network Analyzer

Capsa is an easy-to-use Ethernet packet sniffer (network analyzer or network sniffer) for network traffic monitoring and troubleshooting purposes. It performs real-time packet capturing, 24/7 network monitoring, reliable network forensics, advanced protocol analyzing, in-depth packet decoding, and automatic expert diagnosing. By giving you insights into all of your network’s operations, Capsa makes it easy to isolate and solve network problems, identify network bottleneck and bandwidth use, and detect network vulnerabilities.

Solution 1. Monitor network traffic in the Dashboard tab of Capsa network analyzer

If we want to have a graphical view of the statistics or get a trend chart of the network traffic, then we can use the graphs in the Dashboard tab. It provides a great many of statistic graphs from global network to a specific node. You are able to as well create almost any kind of graph based on any MAC address, IP address and protocol, etc. With these graphs, you can easily find out anomalies of the network and get useful statistics.

Solution 2. Monitor network traffic in the Summary tab of Capsa network analyzer

The Summary tab provides general information of the entire network or the selected node in the Node Explorer window. In the Summary tab we can get a quick view of the total traffic, real-time traffic, broadcast traffic, multicast traffic and so on. When we switch among the node in the Node Explorer window, corresponding traffic information will be provided.

Solution 3. Monitor network traffic in the Physical Endpoint and IP Endpoint tabs of Capsa network analyzer

In these two endpoint tabs (Physical Endpoint and IP Endpoint), we can monitor network traffic information of each physical address node and IP address node, both local and remote. With their easy sorting feature we can easily find out the nodes with abnormal traffic, such as which hosts are generating or have generated the largest traffic.

Solution 4. Monitor network traffic in the Protocol tab of Capsa network analyzer

The Protocol tab lists all protocols applied in your network transmission. In the Protocol tab we can monitor network traffic by each protocol. By analyzing the protocols in the network traffic, we can easily understand what applications are consuming the network bandwidth, for example, the HTTP stands for website browsing, and the POP3 stands for email, etc.

Solution 5. Monitor network traffic in the Matrix tab of Capsa network analyzer

The Matrix tab visualizes all network connections and traffic details in one single graph. The weight of the lines between the nodes indicates the traffic volume and the color indicates the status. As we move the cursor on a specific node, network traffic details of the node will be provided.
