For engineers, architects, and DevOps teams, distributed architectures and reactive applications make pinpointing and fixing production errors in Java and Scala code an increasingly difficult task. In this hands-on, practical video, JVM and debugging expert Tal Weiss reviews the practices Java and Scala developers can use to spot, profile and correct production application issues. He provides a set of advanced techniques that can be put to immediate use for quickly profiling and debugging live servers, and resolving critical errors without impacting performance.

• Review the pros and cons of production debugging using JDK, APM, Log, and Metrics tools
• Discover the importance of injecting state into JVM threads when debugging behavior and performance
• Explore advanced capabilities of jstack and Hotspot debugging tools
• Explore the components, advantages, and disadvantages of JVM debugging architecture
• Create advanced debugging and monitoring functions, using advanced Bytecode instrumentation techniques for both Java and Scala applications
• Write Java agents to profile and collect root cause state from production JVMs
• Wire your Java agents into your DevOps infrastructure using industry DevOps protocols
• Discover the JVM Tooling Interface – the JVM’s lowest level of native API

Tal Weiss builds JVM production debugging tools for high-scale applications. He is CEO at Takipi and was co-founder/CEO at VisualTao (acquired by Autodesk). He’s been designing scalable, real-time Java and C++ applications for 15 years. Tal blogs at blog.takipi.com.
