How do you use VisualVM and Mission Control with a simple code example?

VisualVM and Mission Control are powerful tools for monitoring and managing Java applications. This document provides a simple example to illustrate how you can utilize these tools to analyze performance metrics and JVM behavior.
VisualVM, Mission Control, Java monitoring, Java performance analysis, JVM tools
<?php // Simple Java application example to monitor public class SimpleApp { public static void main(String[] args) { // Simulating a task for (int i = 0; i < 10; i++) { System.out.println("Count: " + i); try { Thread.sleep(1000); // Simulate work } catch (InterruptedException e) { Thread.currentThread().interrupt(); } } } } ?>

To use VisualVM:

  1. Download and install VisualVM.
  2. Run the SimpleApp Java program.
  3. Open VisualVM which will automatically detect the running Java application.
  4. Click on the application to view memory usage, CPU usage, threads, and other metrics.

To use Mission Control:

  1. Download and install Java Mission Control.
  2. Run the SimpleApp Java program with the JVM option: -XX:+UnlockCommercialFeatures -XX:+FlightRecorder
  3. Open Mission Control, and you can view Flight Recorder and diagnostics.
