Using the Diagnostic Commands Tab

Diagnostic commands allow you to monitor the efficiency and performance of your Java application. JDK Mission Control uses a number of different diagnostic tools, including a set of commands that you can run against the application using the Diagnostic Commands tab.

The Diagnostic Commands tab is divided into the following sections:

• The Operations list on the left contains a list of commands you can execute against the application running on the connected JVM.

• The list of command arguments on the right contains the names and values of arguments that you can specify.

• The full command with all arguments that will be executed is displayed at the bottom, next to the Execute button (that runs the command) and the Help button (that displays the command help).

• The result of executing the command or requesting for the command help is displayed in an output panel that expands from the bottom. This panel contains a separate tab for each time you execute a command or request for the command help. In the title of the tab, the date and time of execution is displayed along with the full command.

To run a command, select it in the Operations list, provide the argument values in the table on the right, and click Execute at the bottom.
