What you'll learn

​In production, Java performance issues like memory leaks or sudden latency spikes often feel like "black boxes" - frustratingly invisible and nearly impossible to replicate locally. In this course, Java SE in Practice: Observability and Diagnostics in Production, you’ll gain the ability to stop the guesswork and start using precise, data-driven root-cause analysis. First, you’ll explore real-time monitoring by leveraging Java Flight Recorder (JFR) and Mission Control to capture deep telemetry without crashing your performance. Next, you’ll discover how to interrogate the JVM itself, learning to pull apart thread dumps, GC logs, and heap snapshots to find exactly where your code is choking. Finally, you’ll learn how to bake observability into your stack with production-ready logging and metrics that alert you before a bottleneck becomes an outage. When you’re finished with this course, you’ll have the skills and knowledge of advanced JVM diagnostics needed to reliably troubleshoot live systems and drastically cut down your time to resolution.
