Let's Learn to Talk to GC Logs

Explore the new Garbage Collection (GC) logging framework introduced in Java 9 through this informative conference talk. Dive into the changes brought by JEP 271, which reimplemented GC logging using the Unified JVM Logging Framework. Learn about the new -Xlog JVM option and the category tags for various JVM components. Discover how to use the 'gc' tag with -Xlog:gc and other parameters to enable detailed GC logging for different parts of the GC system. Understand the GC logging options that will be removed in Java 9 and how to achieve equivalent logging with the new mechanism. Analyze sample GC logs generated using the new logging system and gain insights into reading and interpreting them effectively. Benefit from the expertise of Poonam Parhar, a JVM Sustaining Engineer at Oracle, as she shares her experience in resolving complex Garbage Collection issues and improving JVM serviceability and supportability.
