Training

Diagnostics and troubleshooting of Spring Boot apps

Is your Spring Boot application slow, throwing strange errors, or behaving unpredictably? In this hands-on training, you’ll learn to quickly find and fix bottlenecks, configuration errors, memory leaks, and other common problems. We’ll analyze real-world cases, learn to build useful logging and monitoring tools, and develop a systematic approach to diagnostics. Participants will come away with a clear procedure to follow when problems arise and more confidence in supporting their systems.
