Using Wireshark to Troubleshoot Network Connectivity Issues: IO Graphs
In addition to the “Follow TCP Stream” and “Decode As” features, Wireshark also includes a useful tool called “IO Graphs” that allows you to visualize the traffic on your network in a graphical format.
To use the “IO Graphs” feature, simply select the “Statistics” menu and then choose “IO Graphs.” This will open a new window that allows you to customize the graph according to your needs.
You can use the “IO Graphs” feature to identify patterns in the traffic and see how different devices are interacting with each other. For example, if you see a sudden spike in the traffic on your network, you can use the “IO Graphs” feature to identify which device or devices are causing the spike and determine the cause.
You can also use the “IO Graphs” feature to identify any problems with the traffic on your network, such as slow performance or connectivity issues. By visualizing the traffic in this way, you can often identify the root cause of the problem and take the appropriate action to fix it.
With a little bit of practice and a thorough understanding of the features and techniques available in Wireshark, you can become an expert at troubleshooting network issues and keeping your network running smoothly.
