New Performance Tools for Java 7

By Michael Williams, Principal Curriculum Developer

Have you ever wished for an easy way to monitor your application's performance and analyze the application's performance over time? With the release of Java 7 u40, your wish has just come true. 

Two tools are are now bundled with the Java JDK. Both tools have been around for a while as part of Oracle Fusion Middleware, but now have been ported to the Hotspot JVM.

Java Mission Control

Java Mission Control is a live monitoring and analysis tool for Java 7. This tool lets you monitor live data coming from a running JVM. Mission Control has a modern, customizable user interface which allows you to chart only the data you're interested in. In addition, the triggers feature lets you notify specific personnel about key events that occur in your application. Finally, Mission Control can load recordings from Java Flight Recorder for detailed analysis.

Oracle Java Flight Recorder

Oracle Java Flight Recorder is a tool for recording key information about your application over time. Much like an airline flight recorder, Java Flight Recorder stores key telemetry from your application as it runs; it then loads recordings into Mission Control for detailed analysis. Recordings can be run continuously on your applications with minimal impact on performance.

Java Performance Tuning with Mission Control and Flight Recorder Training

Interested in learning more about these tools?

Oracle University has released the new Java Performance Tuning with Mission Control and Flight Recorder course. This course deep dives into Oracle Mission Control and Flight Recorder, along with other interesting performance-related information, including:

  • Details about how garbage collection works in the JVM.
  • A detailed review of the garbage collectors available in Hotspot, including the new G1 garbage collector.
  • Profiling your application using NetBeans and other tools.
  • Detecting and troubleshooting common performance issues like memory leaks and contention issues.
  • Tuning guidelines for each of the Java garbage collectors.
