Garbage Collection (GC) is a cornerstone of Java's memory management, ensuring efficient use of resources by reclaiming unused objects. But how do we monitor and optimize this critical process in real-time? Enter ๐—๐—ฎ๐˜ƒ๐—ฎ ๐—ฉ๐—ถ๐˜€๐˜‚๐—ฎ๐—น๐—ฉ๐— , a powerful tool that gives developers unparalleled insights into GC performance and memory utilization.

VisualVM provides a visual interface to monitor JVM activity, making it easier to analyze garbage collection patterns, detect memory leaks, and optimize heap usage. With features like heap dumps, thread monitoring, and real-time GC visualization, it transforms complex profiling tasks into actionable insights.

  1. Install VisualVM (included in the JDK).
  2. Enable plugins like ๐—ฉ๐—ถ๐˜€๐˜‚๐—ฎ๐—น ๐—š๐—– for enhanced GC monitoring.
  3. Attach VisualVM to your applicationโ€™s JVM to start analyzing GC activity in real time.
