Hello,
Our Education team provides some excellent self-paced training here:
http://www.appdynamics.com/enablement/university/
Around the middle of the page there is a section titled "Self-paced training". The "Accelerator Program" is a great place to start. It is free and covers installation, application monitoring, troubleshooting, and configuration. "eLearning" links you to longer more advanced courses.
If you browse a bit more you will see we also have other training options available as well - much of it free. For example, "Learning Bytes" links you to 2-10 minute training videos on specific topics ranging from "Introduction to APM" to "Utilizing JVM Metrics". Tech Webinars are free live 45 minute sessions that take place every other Wednesday. Topics range from beginner to expert level. Recordings of past webinars are also available through this link.
