How to instrument Weblogic Applications with WLDF -> Where does the application actually spends the time?

The WebLogic Diagnostic Framework (WLDF) is a powerful tool that offers virtually unlimited possibilities to monitor, tune and troubleshoot deployed applications. In this post I will describe how to use WLDF in order to get a better idea on where does an application spend it’s time, broken down by components. This is achieved by using the WLDF application-scoped instrumentation. The main steps for setting it up are:


1. Enable the Diagnostic Context to track down a request throughout the system;
2. Enable server-scoped instrumentation;
3. Enable application-scoped instrumentation;
4. Define specific Diagnostic Monitors and assign them specific Actions;
5. Update the application with the new settings;
6. Access the instrumented application and analyze the collected data;
