WebLogic Diagnostic Framework Console Extension in WLS 9

Have you seen the diagnostic framework in 9.2 recently? You can add a fine console named WebLogic Diagnostic Framework Console extension to the admin console.

Copy the Diagnostic-console-extension.jar file from the Weblogic-install/server/lib/console-ext directory to the Console-ext directory of the domain. If there is no Console-ext directory in the domain directory, create it.

Then restart the Management Server, and now that you are logged into the admin Console, you will see a tab showing the WLDF console extension. Your browser needs Java plug-in,console extension to work.

Its very simple use is to monitor the heap usage of Jvmruntimembean. You can click the properties and drag them to the View panel to view the graphs. There is also the out-of-the-box built-in view. You can also use the console extension to view method performance under the Requests tab.

The advantage of WLDF is that it can not only monitor the real-time information of cached Mbeans, but also interpret wldf harvested (metric) or instrumentation (event) data. With the data in the Harvesteddataarchive log, it can display both current and historical data for you to perform trend analysis.

For more information about the WebLogic Diagnostic framework and for more information about Harvester, instrumentation, and more, see the electronic documentation for the following sites: http://e-docs.bea.com/wls/ docs92/wldf_configuring/
