As an administrator or an operator, you can view, collapse, or expand the Topology. The Topology view is a graphical representation of the relationship among services and the devices that support them. Icons represent the object type, and arrows and the position of icons represent the relationships. CA SOI highlights the selected Object on the Services tab with small boxes.
Note: The Topology view is available in the main Contents pane and in the Service Modeler window. Some toolbar buttons described in this section do not appear on both windows.
Follow these steps:
One or more icons on the Topology pane represent the service.
(Pan Tool)Moves the topology up, down, right, and left when you click the tool and drag on the screen.
Note: You can use the mouse wheel to zoom in and out.
(Select Tool)Displays details about a service or resources when you click the tool then click a service or resource in the right pane. The details appear in the Component Detail area under the Topology.
(Interactive Zoom Tool)Enlarges or reduces the topology when you drag the tool on the screen. Other zoom buttons include the Marquee Zoom Tool and Zoom Level Control.
Note: You can also zoom by using the mouse wheel.
(Link Navigation Tool)Displays relationships to and from objects when you click the tool and mouseover the object. The tooltip describes the relationship. For large topologies, click the relationship link to pan to the linked object at the other end.
(Marquee Zoom Tool)Increases the magnification in a specific region when you click the tool and select a region in the right pane. Other zoom buttons include the Interactive Zoom Tool and Zoom Level Control.
(Relationship Tool)(Service Modeler only) Specifies the type of relationship to create between objects when you click the tool and select one of the available relationships. Once you select a new relationship, all new objects obtain that relationship type.
(Adjust and View buttons)(Contents pane only) Rearranges the topology when you click the Adjust button and drag items. Click Save when you are finished to save the changes. Select the default option button View to disable further changes.
Note: You can also adjust the layout while in View mode when you click Apply Automatic Layout and select a layout from the drop-down list.
(Save Topology Layout)(Contents pane only) Saves topology changes.
(Perform Service Validation)(Service Modeler only) Verifies that a service is complete and correct.
Note: Automatic validation occurs after every change to the service.
(Apply Automatic Layout)Changes the type of chart when you click the button and select one of the following options:
Emphasizes clusters that are present in a network topology.
Arranges objects in horizontal rows and vertical columns.
Emphasizes relationships among objects by placing them at different levels. The layout is like an organizational chart at a company, which is the default when you build services from scratch.
Minimizes bend points by arranging objects horizontally and vertically, at 90 degree angles.
Emphasizes symmetries that are present in a network topology, which is the default for newly discovered services. Symmetric is also the fastest and yields the smallest topologies.
(Refresh Layout Contents)(Contents pane only) Updates the service topology according to recent changes. The topology may require a refresh to reflect the current service topology if the SA Manager has a high processing load, a shutdown of the SA Manager interrupted processing, or a heavy volume of import events are being processed. When you click the button, you get a confirmation message that states one of the following:
(Delete Selected Topology Objects)(Service Modeler only) Removes objects from the service when you select them and click the button.
(Straighten Selected Edges)Removes bends in the links between items when you select a wavy line and click the button. This button is available in the Service Modeler, and in the Contents pane when you click the Adjust option button.
(Undo Last Action)Discards topology changes.
(Redo Last Action)Repeats your last action.
(Chart Complexity Level)Displays the type of relationship among objects when you click the button and select Advanced. Simple is the default in the Contents pane, and Advanced is the default in the Service Modeler. When you select Advanced, the arrows between objects are color-coded and contain the first letter of the relationship type. When you select Advanced with Names, the arrows between objects are color-coded and contain the full name of the relationship type.
(Filter Configuration Item Condition Visibility)(Contents pane only) Emphasizes severities when you click the button and select a severity. Items with severities lower than the one selected are dimmed. For example, if you select Major, items with Normal and Minor severities are dimmed.
For more information, see Severity.
(Change Relationship Visibility)Hides the links between objects when you click the button and select Hide ALL from the drop-down list. Show ALL is the default. On the Service Modeler, you can also select specific relationships (aggregates, bound, and so on).
(Toggle Item Highlighting)(Contents pane only) Enables or disables synchronization with the Component Detail pane. By default, details for the selected item in the topology are displayed, but you may want to turn it off to increase performance when you adjust or navigate the service topology.
(Show/Hide Item List Pane)Displays or removes a table of details beneath the Topology pane.
(Zoom Level Control)Specifies the amount of magnification. Other zoom buttons include Interactive Zoom Tool and Marquee Zoom Tool.
(Toggle Overview Window)Displays a small view of the topology. This window is useful when you want to change the region or zoom level of the topology view.
You can use the following shortcut keys to quickly switch between tools when the Topology pane is active and one of the tools is already selected:
