Using the WebLogic Diagnostic Framework Console Extension

Working with Views

A view is a named collection of charts and graphs that present graphical information of similar diagnostic type data. The Views tab in the left panel provides the means to create, select, modify, and delete views. When you select (click) the name of a view in the Views tab on the left, the view is displayed in the View panel on the right, as shown in Figure 5-1. That view remains displayed in the View panel, even when you select different tabs in the left panel.

The Views tab lists both built-in and custom views.

• Built-in views are a set of predefined views of available runtime metrics. These views surface some of the more critical runtime WebLogic Server performance metrics and serve as examples of the WLDF Console Extension's view and graphing capabilities.

Built-in views are available for every user logged into the Administration Console and using the WLDF Console Extension.

You can modify a built-in view, but the modification is only visible during your current session; it is lost when you switch back to the primary Administration Console view. Also, no other user can access the modified view. If you want to modify and save one of the built-in views, you can clone it and save it as a custom view.

• A custom view is any view created by a user. Custom views are available only to the user who created them. You can save a custom view and access it again when needed.

WLDF Console Extension provides no pre-defined custom views.

The views listed in the Views tab are displayed in separate trees, as shown in Figure 5-2.

Table 5-1 describes the visual cues that help identify the views in the Views tab.

Starting and Stopping a View

When you start a view, polling commences for the charts in the view. That is, the client starts polling for data from the server, so that the data can be represented in one or more graphs. When you stop a view, polling for the view ends.

To start a view:

Click the Views tab.
Right-click the view you want to start, and select Start from the menu.

To stop a view:

Click the Views tab.
Right-click the view you want to stop, and select Stop from the menu.

To stop all views, click the (Stop All Active Views) button on the toolbar to stop all active views.

Note: Current data for Metrics charts is polled from a data cache on the server. Historical data for Metrics charts and all data for Method Performance charts are retrieved from data archives. If you stop all views, data is no longer added to the data cache on the server. For more information, see Understanding How Data Is Collected and Presented.
