A view is a named collection of charts and graphs that present graphical information of similar diagnostic type data. The following sections describe how to work with views:
The Views tab in the Tabs panel, on the left side of the page, contains a list of views for all running servers in the domain. It also 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 Tabs panel.
Figure 5-1 Views Tab and View Panel
The Views tab lists both built-in and custom views.
The Built-in views are a set of predefined views of available runtime metrics for all running WebLogic Server instances in the domain. 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 installed when you install the WLDF Console Extension, and they 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 charts and graphs in a view can display diagnostic data for any of the servers running in the domain.
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.

Displaying and Modifying an Existing View
To display and modify an existing view:
Select the Views tab to display the list of available views.
Click the name of the view. The view appears in the View panel, replacing the view that is currently displayed. (Only one view can be displayed at a time.)
In the Views tab, right-click the view name and select Save Changes, or
On the toolbar, click the (Save All Modified Views) button.
Creating a View Based on an Existing View (Cloning)
To create and display a view based on an existing view:
Select the Views tab.
Click the name of the existing view on which you want to base a new view.
In the text field to the left of the Create button, enter a name for the new view.
Click Clone to copy the current view with the new name. The cloned view is displayed in the View panel. Until you make changes, the cloned view has the same properties as the view upon which it is based.
In the Views tab, right-click the view name and select Save Changes, or
On the toolbar, click the (Save All Modified Views) button.
Changing the Name of a View
You can change the names of custom views only. To change the name of a view:
Select the Views tab.
Right-click the name of the view you want to rename, select Rename, and type a new name. Alternatively, in the View panel, right-click the name of the current view at the top of the panel. Then type a new name in the field.
Save the view:
In the Views tab, right-click the view name and select Save Changes, or
On the toolbar, click the (Save All Modified Views) button.
Saving A Custom View
While you can modify any view for the current session, you can save only custom views. To save a custom view:
Select the Views tab.
Click the name of the custom view you want to save.
Save the view:
In the Views tab, right-click the view name and select Save Changes, or
On the toolbar, click the (Save All Modified Views) button.
Deleting a View
You can only delete custom views. To delete a custom view:
Select the Views tab.
Click the name of the view you want to delete.
Click the (Delete) button in the toolbar.
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:
Select the Views tab.
Either left-click the view you want to start, or right-click and select Start from the context menu.
To stop a view:
Click the Views tab.
Right-click the view you want to stop, and select Stop from the context 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.
(Stop All Active Views) button on the toolbar to stop all active views.
