Viewing a CI topology
When you are viewing a single authorized configuration item (CI) in the Configuration Items application, you can use the Topology subtab to view a graphical representation of the CI and its relationships with other CIs.
About this task
The Topology subtab shows a main view, containing a graphical representation of the CI and its relationships with other CIs, and control areas on the right side. You can zoom in and out and perform other manipulations using the row of controls at the top of the topology view.
The Overview pane in the upper right portion of the screen contains a miniature view of the topology map. You can use it to control the larger view.
The Filter pane
to the right of the main view provides filters that you can use to
control the following aspects of the topology graph:
- Views
- You can use the radio buttons to choose between two views of CIs
in the topology:
- Detail View
- This view shows all related CIs of all types.
- Business View
- This view shows a subset of all CI types. The types that are shown are those that have been designated for inclusion in this view by checking Show in Business View for this CI type in the Classifications application. By default, certain CI types are designated for the business view, such as application servers, services, and so on; CIs such as NIC cards, storage devices, and so on are not included in the business view. CI types that are set for the business view are typically those that can have a substantial impact when taken out of service.
- Show Impacted
- Select this checkbox to see which other configuration items are
affected by an outage of the current CI. If you select this checkbox,
an impact icon
is displayed next to any CI that is affected by
an outage. - Breadth
- The number of levels of relationship to show in the view. The initial breadth and maximum breadth are contained in the system properties pmgui.citopology.depth and pmgui.citopology.init. An administrator can configure these system properties to change the initial and maximum breadth.
- Relationships
- The types of relationships to include in the view. The list shows all the relationship types that exist between nodes in the diagram. You can exclude relationship types if you want to see only certain types. The lines between nodes that do not have one of the relationships you have included are grayed out.
- Classifications
- The types of CIs to include in the view. The default is all types. You can choose to exclude some types if you do not want to see them. CIs of the excluded types are not displayed in the diagram.
Use the following tips and
guidelines to examine information about target and related CIs in
the topology view:
- Each target CI node has a double border.
- Hover over a node to see the full name and description of the CI.
- A status icon is displayed in the upper left corner of each node. Hover over the icon to see a text description of the status.
- Right-click a node and select CI information to open a dialog that shows more CI properties. The dialog also shows tasks that are scheduled to have an effect on this CI. For example, a scheduled task might have this CI as a target.
- If a CI node shows a wrench icon (
) in the left central
portion of the icon, that CI is the target of a task that is in progress.
To see the work items, choose the View Work Details action. - If a CI shows an alert icon (
) in the lower left
portion of the icon, one or more incidents have been opened that affect
the CI. Hover over the icon to see more information. - Hover over a link between two connected CI nodes to see the relationships that exist between the two connected CIs.
