VisualVM

VisualVM is a free open source performance monitoring and profiling tool for Java applications. It enables developers to monitor Java application statistics, troubleshoot performance issues, and perform memory and CPU profiling.

What is VisualVM?

VisualVM is a versatile performance monitoring and profiling tool for Java applications. It is designed to help developers optimize, troubleshoot, and understand the runtime behavior of their Java code.

Some key features of VisualVM include:

  • Monitoring memory usage, CPU utilization, threads and other statistics for Java applications
  • Performing CPU and memory profiling to identify hotspots, leaks, and bottlenecks
  • Generating detailed heap dumps and thread dumps for analysis
  • Integrating with JMX to monitor MBeans and perform operations
  • Tracing method calls to understand bottlenecks and hot paths
  • Attaching VisualVM to local and remote JVM processes
  • Pluggable architecture to extend functionality via plugins

VisualVM provides both real-time performance insight as well as historical data on key metrics. The intuitive user interface makes it easy for developers to pinpoint issues and improve application efficiency. With its profiling capabilities and flexibility via plugins, VisualVM is feature-rich tool for understanding Java application behavior.
