state of the art in Java EE debugging and monitoring tools

I'm digging into Ja开发者_JS百科va EE for the first time in years. I'm looking for recommendations on Java EE debugging and monitoring tools. I'd like to find a tool that lets me dynamically explore the threads space etc.

I'm primarily working with Tomcat. update: and Java 5. (Rats.)


If you are unable to use VisualVM (not sure how it plays with Java5 instances), take a look at Lambda Probe.

Lambda Probe may not have all of the features you want (e.g. threads), but does have quite a few monitoring features and works with Java 4 and 5.

  • New! Comprehensive JVM memory usage monitor.
  • JBoss compatibility
  • Display of deployed applications, their status, session count, session object count, context
    object count, datasource usage etc.
  • Start, stop, restart, deploy and updeploy of applications
  • Ability to view deployed JSP files
  • Ability to compile all or selected JSP files at any time.
  • Ability to pre-compile JSP files on application deployment.
  • New! Ability to view auto-generated JSP servlets
  • Display of list of sessions for a particular application
  • Display of session attributes and their values for a particular
    application. Ability to remove
    session attributes.
  • Ability to view application context attributes and their values.
  • Ability to expire selected sessions
  • Graphical display of datasource details including maximum number of
    connections, number of busy
    connections and configuration details
  • New! Ability to group datasource properties by URL to help
    visualizing impact on the databases
  • Ability to reset data sources in case of applications leaking
    connection
  • Display of system information including System.properties, memory
    usage bar and OS details
  • Display of JK connector status including the list of requests
    pending execution
  • Real-time connector usage charts and statistics.
  • Real-time cluster monitoring and clulster traffic charts
  • New! Real time OS memory usage, swap usage and CPU utilisation
    monitoring
  • Ability to show information about log files and download selected
    files
  • Ability to tail log files in real time from a browser.
  • Ability to interrupt execution of "hang" requests without server
    restart
  • New! Ability to restart Tomcat/JVM via Java Serview Wrapper.
  • Availability "Quick check"
  • Support for DBCP, C3P0 and Oracle datasources
  • Support for Tomcat 5.0.x and 5.5.x
  • Support for Java 1.4 and Java 1.5


The state-of-the-art is probably VisualVM.
