The JVM Monitor is a Java analyzer integrated with Eclipse that monitors CPU, thread, and memory usage of Java applications. The JVM monitor will help you quickly examine your Java application without having to prepare any startup configuration beforehand.

The JVM monitor automatically finds running JVMS on the localhost, and you can easily start monitoring them. It also supports monitoring Java applications on remote hosts by providing host names and port numbers.

Note five core knowledge modules, everyone look and see if they know:

  • Approached Java
  • Automatic memory management
  • Virtual machine execution subsystem
  • Program compilation and code optimization
  • Efficient concurrent

This is just the five modules in the notes, the specific knowledge point analysis, you continue to look!
