1. Monitoring tools available in the JDK

JDKs 5 and 6 from Oracle include APIs and a mix of standard and experimental tools for monitoring, profiling, and troubleshooting applications. Chief among them is JConsole, introduced in Java SE 5 and officially supported (and enhanced) in Java SE 6. Learn how to use JConsole and other JDK facilities for monitoring and managing JVM behavior.

About this knowledge path

Tracking the source of Java application bottlenecks is critical to the application-development cycle. With the introduction of better profiling tools and a host of diagnostic tooling from the IBM Java team and others, the task of monitoring and diagnosing Java applications has become considerably less difficult than in the past. In this knowledge path, you'll learn more about the tools you can use to assess and improve the health of your applications effectively.
