Roadmap
The WebLogic Diagnostic Framework (WLDF) Console Extension is a part of the WebLogic Diagnostic Framework that provides views and tools for graphically presenting diagnostic data about servers and applications running on them. The underlying functionality for generating, retrieving, and persisting diagnostic data is provided by the WLDF framework, and the WLDF Console Extension provides additional tools for presenting that data in tables, charts, and graphs.

What Is the WebLogic Diagnostic Framework Console
Extension?
The WebLogic Diagnostic Framework (WLDF) Console Extension is a part of the WebLogic
Diagnostic Framework that provides views and tools for graphically presenting diagnostic data
about servers and applications running on them. The underlying functionality for generating,
retrieving, and persisting diagnostic data is provided by the WLDF framework, and the WLDF
Console Extension provides additional tools for presenting that data in tables, charts, and graphs.
The WLDF Console Extension is implemented as an extension to the WebLogic Server
Administration Console, using the WebLogic Server Console Extension architecture (see
Extending the Administration Console).

CHAPTER 2
Installing and Displaying the WLDF
Console Extension
The WebLogic Diagnostic Framework (WLDF) Console Extension is included with WebLogic
Server, but it is not installed by default. The following section describes how to install and display
the WLDF Console Extension:
“Installing the WLDF Console Extension” on page 2-1
“Displaying the WLDF Console Extension” on page 2-3
Installing the WLDF Console Extension
The WLDF Console Extension is delivered as a Java Archive (JAR) file, named
diagnostics-console-extension.jar. You must install this JAR file into the
Administration Server for a domain for the WLDF Console Extension to be incorporated into the
WebLogic Server Console for that domain.
Installation Prerequisites
Before you can install and run the WLDF Console Extension, you need:
WebLogic Server 9.1 or higher installed
A Web browser that meets the requirements for running the Weblogic Server 9.1 or higher
Administration Console
Java Plug-in version 1.5 (J2SE Runtime Environment 5.0)
Java and JavaScript enabled in your browser
Using the WebLogic Diagnostic Framework Console Extension 2-1
Installi ng and Displayi ng the WLDF Console Extension
Installing the Java Plug-in
For browsers other than Mozilla or Firefox in a Linux environment, if the Java plug-in 1.5 is not
already installed in your Web browser, you will be prompted to initiate a download from the Sun
Microsystems Java Web site. Follow the instructions on screen.
Alternatively, install the plug-in manually when you begin the installation process for the WLDF
Console Extension:
1. Go the Java Software download page, at:
http://java.com/en/download/
2. Follow the instructions on screen.
If you are using Mozilla or Firefox on a Linux machine, you must install
libjavaplugin_oji.so into your /plugins directory.
Installing the WLDF Console Extension
To install the WLDF Console Extension:
1. Find the diagnostics-console-extension.jar file in the
WL_HOME\server\lib\console-ext directory, where WL_HOME is the directory in which
you installed WebLogic Server.
2. Copy diagnostics-console-extension.jar into the DOMAIN-DIR/console-ext
directory for every domain in which you want to use the Console Extension, where
DOMAIN-DIR is the domain's root directory.
3. 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.
Enable or disable the WLDF Console
You can enable or disable the WLDF Console Extension from the Administration Console:
1. In the banner toolbar region at the top of the right pane of the Console, click Preferences (to
the right of the Logout link).
2. Select the Extensions tab.
3. In the list of extensions at the bottom of the page, select the check box for
diagnostics-console-extension and click Enable to enable the extension or Disable to disable
it.

4. Restart the Administration Server for the domain where you enabled or disabled the
extension.
Removing the WLDF Console Extension
To remove the extension:
1. Stop the Administration Server.
2. Delete the JAR file from the DOMAIN-DIR/console-ext directory and restart the
Administration Server.
Displaying the WLDF Console Extension
When you launch an Administration Console in which the WLDF Console Extension is installed,
the Console appears with two tabs, Oracle WLS Console and WLDF Console Extension, as
shown in Figure 2-1.
Figure 2-1 Console Extension Tab
By default, the Oracle WLS Console tab is initially selected on login, which shows the standard
Administration Console. Select WLDF Console Extension to display the extension.
These two tabs are always present, so you can easily move back and forth between the primary
Administration Console pages and the WLDF Console Extension.
Note: All WLDF Console Extension functionality occurs in the context of a Java applet. Each
time you select the WLDF Console Extension tab, the applet is loaded.
When you select the Oracle WLS Console tab, the applet is unloaded, and you are
returned to the Administration Console context that existed before you displayed the
WLDF Console Extension. All activity related to the applet and the WLDF Console
Extension is terminated.

Look and Feel Support
The WLDF Console Extension does not implement a specific look and feel (that is, the visual user
interface design). Rather, it adopts the look and feel of the environment in which the WLS
Administration Console is running:
For non-Windows systems, the Console Extension uses the look and feel specified in the
Java environment.
For Windows systems, the Console Extension uses the default Windows look and feel.

CHAPTER 3
Overview of the WLDF Console
Extension
The WLDF Console Extension provides a set of visual tools you can use to directly manipulate
objects to display diagnostic information about WebLogic Server instances. The following
sections provide a high level overview:
“Scope of the Diagnostic Information Displayed”
“Two Main Panels”
“View Panel Overview”
“Tabs Panel Overview”
“Toolbar and Status Bar Overview”
“Displaying Tooltips for Controls, Views, Graphs, and Charts”
“Creating Views, Graphs, and Charts: Main Steps”
“Alternative Ways to Manipulate Objects”
Scope of the Diagnostic Information Displayed
You install the WLDF Console Extension into a domain, and you can display diagnostic data
about any of the server instances in that domain and about applications running on those servers.

Two Main Panels
The WLDF Console Extension has two panels, the Tabs panel and the View panel, plus a toolbar
and a status bar, as shown in Figure 3-1.
Figure 3-1 WLDF Console Extension Panels
View Panel Overview
A view is a collection of one or more charts, which display captured monitoring and diagnostic
data, as shown in Figure 3-2 and Figure 3-3. Views are displayed in the View panel, on the right
side of the WLDF Console Extension page. The View panel displays a single view at a time.

Overvie w of the WLDF Consol e Exte nsi on
Each chart contains a legend, labels, and controls for identifying and displaying the data. A chart
can display data from one or more data sources from one or more servers in the domain. The data
sources include one or more metrics (that is, the value of an MBean instance attribute) or one or
more instrumented methods. Each data source is displayed as a distinct graph, which shows the
values of data points over a time span. The relationship between views, charts, and graphs is
shown in Figure 3-4. In the figure, the view contains two charts, “WLDF Metrics Chart” and
“JVMRuntime@MedRecServer,” based on metrics data from the MedRecServer server. “WLDF
Metrics Chart” contains one metrics graph, “UpTime@MedRecServer.” The
“JVMRuntime@MedRecServer” chart contains two metrics graphs,
HeapSizeCurrent@MedRecServer” and “HeapFreeCurrent@MedRecServer.”
Notes: A chart can include graphs based on data from one or more servers in the domain.
You cannot mix metrics graphs and method performance graphs in the same chart.

Tabs Panel Overvi ew
Tabs Panel Overview
The Tabs panel, on the left side of the page, contains tabs with controls for creating and
modifying the views and charts that are displayed in the View panel, on the right.
The Tabs panel contains four tabs:
Views contains a list of built-in views and custom views. It also contains controls for
creating, modifying, and deleting views. See Chapter 5, “Working with Views.”
Metrics contains a tree of all known runtime MBean types, instances, and attributes for the
selected server. You can drag attributes onto a view to create one or more graphs that show
