Java Observability: Production JVM Diagnostics, JFR, GC, CPU

This course contains the use of artificial intelligence.

Debug, profile, and fix mission-critical Java applications directly in production environments with confidence.

Course Curriculum

• Senior Java Developers looking to master JVM internal mechanics and performance tuning.

• Software Engineers responsible for diagnosing production crashes, memory leaks, and CPU spikes.

• System Architects designing resilient Java SE applications requiring real-time telemetry.

• Site Reliability Engineers (SREs) supporting enterprise Java deployments.

• Capture and analyze production heap dumps using Eclipse MAT and JDK Mission Control

• Trace performance bottlenecks in real time using JDK Flight Recorder (JFR)

• Instrument Java applications with OpenTelemetry SDK and Micrometer metrics

• Diagnose complex thread deadlocks, high CPU usage, and lock contention

• Monitor garbage collection behavior and eliminate long GC pauses

• Automate diagnostic capture scripts for high memory and execution anomalies

• Apply thread pool optimization strategies to eliminate execution starvation

• Identify and resolve ThreadLocal memory leaks in application containers

• Formulate action plans to debug zero-downtime production incidents

• Analyze real-world failure case studies to prevent enterprise outages

• Intermediate knowledge of the Java programming language (Java 11 or higher).

• Basic familiarity with command-line tools and terminal navigation.

• Development environment capable of running Java SE SDK 17+ and JDK Mission Control.
