Long garbage collector pauses observed in a productive Java application were initially seen as isolated events, but further investigation uncovered deeper, systemic issues. By leveraging the tools and features available in the JVM, JDK, and the operating system, along with detailed data analysis, the root causes were successfully identified and eliminated.

This session focuses on how to monitor and diagnose performance issues in a Java environment. Key topics include the collection, analysis, and interpretation of critical data from OS statistics, JVM logs, Java Flight Recordings, heap dumps, and thread dumps. The session also covers JVM memory organization and management, providing insight into the impact of garbage collection on performance. Additionally, resources for further exploration of the topic will be shared.

Attendees will gain practical knowledge and tools to identify, resolve, and prevent performance bottlenecks in Java applications, ensuring more efficient and reliable software in production environments.
