This presentation will discuss and demonstrate the WebSphere Application Server Troubleshooting and Performance Lab on Docker which is a free, publicly downloadable Traditional WAS and WAS Liberty troubleshooting and performance lab.
This presentation will cover the basics of the lab itself, how to install and use it, and demonstrate some of the key WAS-related troubleshooting and performance tools that administrators should use day-to-day.
Afterwards, you can download the lab yourself. It is hosted on Docker Hub, so it's just a matter of installing Docker on Windows, Mac, or Linux, downloading and running the lab, and opening a remote GUI into it. You may run through the full lab which is over 130 pages or run it a la carte to learn about topics such as CPU usage, thread dumps, garbage collection, memory analysis, profiling, and more.
For more information, see a demo on YouTube.
