Wireshark Advanced Troubleshooting

In modern IT environments, performance problems are rarely clear-cut. Long response times, packet loss or fluctuating throughput are often just symptoms. The actual cause often lies in the interaction between TCP mechanisms, network infrastructure, servers and applications.

This Wireshark expert course is aimed at experienced users who want to investigate complex faults in a structured manner and make reliable statements. The focus is on a methodical approach for analyzing complex trace files - both for single measurements and for multi-point analyses.

You will deepen your understanding of the behavior of TCP. You will also reliably recognize packet loss and throughput problems and learn to clearly distinguish network causes from server- or application-related effects. The analysis of typical application protocols such as TLS, HTTP(S), SMB, DNS and Citrix is covered in a practical way.

The course is strongly practice-oriented: Using realistic case studies, you will work with anonymized trace files from production-related scenarios. In this way, you not only train individual analysis functions, but also develop the ability to systematically penetrate complex faults and document them in a comprehensible manner.

• Measurement Techniques for Analyzing Complex Problems

This course is aimed at experienced Wireshark users who have basic knowledge of TCP/IP analysis and would like to expand their skills in structured troubleshooting and analysis of complex problems.

You have a good knowledge of the functions of TCP, UDP and IP as well as solid practical experience in using Wireshark and analyzing TCP/IP. The course Wireshark Protocol Analysis - Practical Use in the Network is particularly suitable as preparation.

The aim of the Wireshark workshop is to acquire practical skills in the analysis and troubleshooting of networks and TCP/IP-based applications using Wireshark and to be able to analyze and solve complex error patterns independently.
