JavaOne 2026 Session

Summary

Understanding how to monitor and optimize Java applications is fundamental to building efficient software.

This hands-on lab will introduce how to capture data to understand your application behavior using JDK Flight Recorder (JFR), manage and analyze JFR recordings, and guide you through creating custom JFR events. We'll also cover how JFR can integrate with Prometheus to correlate application and infrastructure behavior, all aimed at enhancing observability.

After this lab, you'll have the confidence to use JFR to monitor, diagnose, and fine-tune your applications.
