Performance analysis and diagnostic aid for Java applications

I just tried the latest iteration of the VisualVM tool, which just released a beta. Very impressive, especially the GlassFish related capabilities. I wonder if there is comparable tooling for other application servers. Here is the functionality in a nutshell:

  • Monitoring and performance analysis for Java SE and EE
  • Integrates the features of several JDK tools
    • jps, jinfo, jstack, jmap, and more
  • Provides lightweight memory and CPU profiling
    • Designed for both development and production
  • Can observe JDK 1.4.2 or higher
  • Provides APIs for writing add-on plugins
Nota bene: If you want to monitor GlassFish apps you'll have to get the plugin from the tool's update center: Tools | Plugin and also some minimal GlassFish configuration is required: In the admin console go to Application Server | Monitor | Runtime | Configure Monitoring and set Web Container to "High". You can also try and use this http://localhost:4848/configuration/monitoringService.jsf?configName=server-config  to open the configuration
