Monitoring garbage collection (GC) is crucial for Java performance. The choice between commercial and open-source GC log analyzers depends on features, platform support, integration, cost, support, maintenance, and vendor lock-in. GCeasy uniquely offers both commercial and open-source advantages, making it suitable for diverse organizational needs while supporting various Java platforms.
Garbage collection (GC) efficiency in Java significantly affects system performance. Proper monitoring of GC logs is essential for tuning the heap and identifying performance issues. Various GC log analyzers like GCeasy, GCViewer, IBM GCMV, VisualGC, and Garbagecat offer insights and recommendations, improving application responsiveness and resource management.
ZGC, an advanced garbage collector for the JVM, enhances Java performance by ensuring efficient memory management, particularly for large applications. Official since JDK 15, it maintains short pause times, but requires considerable CPU resources. ZGC tracks object status using reference coloring, and its relocation process effectively minimizes garbage collection interruptions, promoting scalability.
Java applications utilize two types of memory: Java Heap and Native Memory. The Java Heap stores application objects and is managed by the Garbage Collector, while Native Memory contains essential runtime structures. Understanding these differences aids in diagnosing performance issues and resolving memory-related errors effectively, enhancing application performance and stability.
Native memory leaks in Java are infrequent but challenging to address. This post outlines methods for identifying and troubleshooting leaks, highlighting native memory regions like Metaspace, Threads, and Direct Buffers. By employing tools such as Native Memory Tracking (NMT), developers can effectively diagnose and manage these potential problems.

Automatic garbage collection (GC) in Java aids development but can cause performance issues, especially in time-critical applications. Monitoring and tuning GC is crucial for optimal system performance. Various tools, including built-in JVM utilities and external options like IBM GCMV and GCeasy, can analyze and monitor GC activities effectively.
This post discusses the importance of analyzing Garbage Collection (GC) behavior in production environments for application performance, memory troubleshooting, and capacity planning. It addresses challenges in managing numerous JVMs and presents GCeasy's REST API as a solution for automating GC log analysis, offering insightful metrics and secure data handling options.
The JVM offers various garbage collection (GC) algorithms, with the Mark-Sweep-Compact algorithm being fundamental. This method identifies and frees unused memory through three phases: Mark, Sweep, and Compact. Monitoring GC performance is crucial as inefficient tuning can hinder application performance, making tools like GCeasy valuable for analysis and diagnostics.
