visualvm: Introduction to VisualVM

visualvm: Introduction to VisualVM: "VisualVM is a tool that provides detailed information about Java applications while they are running. It provides an intuitive graphical user interface that allows you to easily see information about multiple Java applications. Java applications are run by a Java Virtual Machine, or VM. The name VisualVM comes from the fact that VisualVM provides VM information visually. As of October, 2007 VisualVM is still under development and is therefore considered an experimental tool. All feedback and suggestions are welcome! Please send your ideas to feedback@visualvm.dev.java.net. System Requirements The VisualVM tool itself must be run with JDK 6. It can display information, however, on any Java application that is running on JDK 1.4.2 or higher. The amount of information VisualVM can provide on a Java application is determined by the version of the JDK that is being used to run that Java application (more details below)"
