Configure and capture diagnostic images

The diagnostic image functionality provided by the WebLogic Diagnostic Service gathers the most common sources of key server state used in diagnosing problems and packages that state into a single file, or "diagnostic image." In the Administration Console, you can specify the default destination directory where diagnostic images for a server are saved, and you can initiate an immediate capture of an image for a server. You can also define a notification to save a diagnostic image based on a watch rule.

If WebLogic Server is configured with Oracle JRockit, and JRockit Flight Recorder is enabled, the diagnostic image capture includes WebLogic Server diagnostic data in a JRockit Flight Recorder file, which can be viewed in JRockit Mission Control. The volume of data that is produced for the Flight Recorder file in the diagnostic image can be customized. To use this capability, you must enable JRockit Flight Recorder and set the WLDF diagnostic volume to Low, Medium, or High.
