GC Log Analyzer

Version 25.01.0

Detailed Metrics for Java Applications

Azul’s Garbage Collector Log Analyzer (GC Log Analyzer) is available in two packages, CA and SA. The CA version is freely available for Azul Zing Builds of OpenJDK (Zing). The SA version is available for customers and supports Azul Zulu Builds of OpenJDK (Zulu) and OpenJDK, as well as Zing.

Use GCLA to view and interpret Java heap, pause time, and operating system metrics gathered while running the Azul Zulu and Azul Zing Builds of OpenJDK, guiding you to make the correct optimizations for your specific Java application. The GC Log Analyzer offers significantly reduced memory usage and faster loading of large Garbage Collector log files. In addition, it offers graphs to give an insight into the Just-in-time (JIT) compilation activity.
