Visualizing Network Traffic with Wireshark
This course will teach you how to use the graphing features within Wireshark to visualize packet data, making network problems easier to find.
What you'll learn
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.
