As a network analyst it can be easy to get lost in the details of a packet trace, when troubleshooting a network problem. In this course, Visualizing Network Traffic with Wireshark, you’ll gain the ability to troubleshoot network problems using the traffic graphing features. First, you’ll explore how to measure overall throughput using the I/O graph. Next, you’ll discover how to use the TCP Stream graphs to troubleshoot slow file transfers over TCP. Finally, you’ll learn how to track client and server dependencies and spotlight problem connections with the Flow Graph. When you’re finished with this course, you’ll have the skills and knowledge necessary to use the Wireshark graphs to quickly pinpoint problems with throughput and slow network transfers.

Course Overview
Hi everyone. My name is Chris Greer, and welcome to my hands‑on course, Visualizing Network Traffic with Wireshark. I'm a network analyst at Packet Pioneer, and I'm excited to dig into the graphing features of Wireshark that make packet analysis much more simple to do. Let's face it, it's easy to get lost in the details of a packet trace when we're troubleshooting a network problem, no matter how much experience we have. If you've ever felt that way, then this course is for you. We're going to learn how to use traffic graphs within Wireshark that make pinpointing the cause of slow file transfers and applications much easier to spot. Some of the major topics that we'll cover include troubleshooting with the I/O graph, finding problems in TCP flows using the stream graphs, and mapping host conversations with the flow graph. By the end of this course, you will know how to interpret the traffic graphs in Wireshark to find network problems faster. Before beginning the course, you should be familiar with the basics of using the Wireshark analyzer and be comfortable with the TCP protocol. I hope that you'll join me on this journey to learn how to find problems faster with the course, Visualizing Network Traffic with Wireshark, here on Pluralsight.
