WLDF provides a mechanism for adding diagnostic code to Oracle WebLogic Server instances and the applications running on them. Monitors, actions, context are the three key diagnostic features provided by WLDF instrumentation.
Consider a WebLogic instance that reports several failures with respect to multiple subsystems and applications. Logging and debugging is enabled for all the subsystems including configuring diagnostic monitors to capture diagnostic data at the both the system and application levels. If the requirement is to be able to perform the analysis in both online and offline modes, You need to configure diagnostic archive that will help you for meeting the requirement.
cp WL_HOME/server/lib/console-ext/*.jar .
Restart the Administration Server for the domain where you installed the extension. The Administration Console for the domain is then deployed with the WLDF Console Extension. Now you can see the difference on the WebLogic console with WLDF tab..
