Excellent free one-day hands-on training

How to search for a needles-in-a-hay-stack (and find them!).

In close cooperation with Wireshark core developer Sake Blok.

The Open Source product Wireshark is a well-known packet analyzer. It is a must-have tool for all network engineers when troubleshooting application and network issues.

However, with these turbo-charged gigabit Ethernet networks, the high level of application virtualization (i.e. micro-services) and multiple security zones/segments in a data-center, troubleshooting can be a real challenge; it is more like searching for needles-in-the-hay-stack!

What you will learn

In this one-day training, you will learn different ways of troubleshooting application issues in these kind of infrastructures; all supported with Wireshark.

We have a real packed agenda for the day:

  • Troubleshooting with Wireshark in high-speed networks (virtualized and non-virtualized)
  • Troubleshooting on 2 or more applications simultaneously across 2 or more sites (with up to 3-Gbps of traffic)
  • Simultaneous troubleshooting numerous applications simultaneously across 2 or more security zones in a data center (with up to 13-Gbps of traffic)
  • Dutch-only(!): behind the scenes of Wireshark (by Wireshark core developer Sake Blok).
  • Diagnose your own packet captures

Expected results

At the end of the day, you will leave with:

  • Hands-on experience on troubleshooting application issues in high-speed networks (virtualized and non-virtualized).
  • Pre-configured virtual network tap (i.e. VM based on Ubuntu and Open vSwitch)
  •  < Profitap? >
  • A 2-weeks working installation of the NPM/APM solution called PVX.

This allows you to start monitoring/troubleshooting applications in your own network.

Target audience

As mentioned previously, this is a real hands-on, technical training designed for server- and network specialists (i.e. architects and engineers) responsible for assuring applications, servers and networks run like clockwork.


The majority of the day is spent on analyzing packet captures with VoIP, web and database traffic. To get the most out of this training we strongly recommend a laptop with the following capabilities:

  • Local administrator rights
  • Wi-Fi as well as wired connectivity
  • Wireshark, VM-player and Java.

While Linux and IOS systems are supported, the exercises assume Windows 7 or better. When registering, use the comments section to describe your Linux or Apple system.

The technical setup

The main components of the technical setup are

  • 1 ESX host running the supportive VM’s (i.e. NGINX, Tomcat and MySQL).
  • 2 VoIP gateways
  • Profishark model <xxx>, ProfiSight, Profitap NPB model <yyy>
  • Application and network simulators
  • Accedian PVX

The troubleshooting parts are based on Wireshark, Profisight (Profitap) and PVX (Accedian).

Special thanks to…

Fast troubleshooting with PVX!
For rock-sold packet capturing and TCP session data analysis

… for making this happen!

Doing some math…

Did you know that a single gigabit Ethernet connection can deliver over 100 MBytes of packet data… each second!?

Which is about 0.4 TBytes every hour and 25 TBytes during a typical workweek; assuming a week with 5 working days and 12 hours per day.

How would you determine which packets belong to the application users are complaining about?

Which of these TBytes of packets would you need to analyze for fixing the issues?
