Using Wireshark to Troubleshoot Network Connectivity Issues: Graphical Time Sequence (grep)
In addition to the “Follow TCP Stream,” “Decode As,” “IO Graphs,” “Expert Infos,” “Time Sequence Graph (tcptrace),” and “Conversation Filter” features, Wireshark also includes a tool called the “Graphical Time Sequence (grep)” feature that allows you to visualize the flow of traffic between two devices over time in a graphical format.
To use the “Graphical Time Sequence (grep)” feature, simply select the “Statistics” menu and then choose “TCP Stream Graphs -> Time-Sequence Graph (Stevens).” This will open a new window that allows you to choose the stream that you want to visualize.
The “Graphical Time Sequence (grep)” feature shows the flow of traffic between two devices over time, with the x-axis representing time and the y-axis representing the sequence numbers of the packets being sent. You can use this tool to identify any problems with the flow of traffic, such as delays or missing packets.
By using the “Graphical Time Sequence (grep)” feature in combination with other diagnostic tools, such as the “Follow TCP Stream” and “IO Graphs” features, you can gain a deeper understanding of the traffic on your network and identify potential problems. 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
