Again, it is only showing you data flowing in one direction. So if a client is downloading a file from an FTP server you must click on a packet from the server before generating the graph. By definition, a stream is moving in one direction. The Time-Sequence graph shows a data stream over time. I’ll be showing you how to use the time sequence graph in my next video, but for now let’s talk about how to interpret the lines and colors and markings. At a glance I can tell if this is going to be an easy one to analyze or if I’m gonna have to roll up my sleeves and dive in deeper.
If I’m troubleshooting a performance issue, one of the first tools I reach for in Wireshark is under Statistics > TCP StreamGraph > Time-Sequence Graph (tcptrace).
