Top View Component

When creating a custom page, Top View can be used as an independent component using its built-in view selector, or together with another component which selects views such as View Explorer. For details, see Set up My Workspace.

Top View presents an interactive map of the CIs that can be manipulated using the mouse, enabling you to focus on specific branches of the tree that are related to particular business or problem areas.

By default, the Top View component displays four levels of CIs. The rest of the CIs are collapsed. You can expand CIs from the fourth level and see their child CIs. The lines connecting the CIs represent the branches of the tree. For detailed information about how to change the number of CI levels displayed in Top View, see How to Customize Top View.

By default, the maximum number of displayed child CIs of a view root CI is 100. However, in large CI topologies, this number can be easily exceeded. In this case, the child CIs are evenly distributed into virtual folders so that not too many CIs are displayed at once, and therefore, any potential performance issues are avoided. Each virtual folder shows the number of contained CIs. After expanding it, you can view the contained CIs in three different layouts (hierarchic, circular, or organic).

You can customize various aspects of Top View such as the Top View layout, CI, KPI, or HI display options, the background image, and so on.

For details on customizing Top View, see How to Customize Top View.

Selecting a view from the drop-down list of the Top View component or any of the wired components on the same page shows CIs in that view. The CI that you select in any of the wired components is automatically selected in other components. For example, if you select a CI in the View Explorer component, this CI is automatically selected and centered in the Top View component, and sub-branches are expanded if necessary.

You can quickly determine the status of CIs in a topology by checking icons and colors that indicate the CI health status. The view is automatically updated when the event status is changed or a new event is received, as well as when there is a change in the CI topology (for example, when a new CI is discovered).

By default, CIs are shown without their KPIs. To display KPI icons for CIs, click the Options button, and then switch the Show KPIs option on. You can also choose to show only the KPIs that have the normal status. In this case, make sure you switch the Show KPIs with normal status option on.

KPIs are displayed with severity icons and colors based on their current statuses. To view a list of a CI's KPIs and their statuses, either click a KPI icon or open the CI context menu by hovering over the selected CI and clicking the Open CI Context button that appears on the right. In the latter case, for more details, open the display view by clicking the right arrow button. Go back by clicking the left arrow button or close the display view by clicking the X button.

To display HI information, click the Options button, and then switch the Show Health Indicators option on. Each CI that has HIs assigned has displayed. To view HI details, click or open the CI context menu. For more information about the data displayed, see Health Indicators Component.

To search for a specific CI in Top View, type any part of a CI name in the Search bar. A list of all matching CIs in that view appears. Selecting a CI focuses on that CI and the branches are expanded if necessary.

If you want to focus only on a particular part of a CI topology, hover over the root of a subtree that you want to view closely, and then click the Show subtree only button that appears on the left. The selected subtree is displayed. If necessary, you can repeat this action to focus even further on the subtree.

To go one level up in the subtree, click the up arrow on the top left of the page. To leave the Show subtree only mode completely, click the X button on the top left of the page. The focus is kept on the last CI you selected.

You can also use the Show subtree only button in the CI context menu. For details, see CI Context Menu.

To view CIs in the layer layout, select Layer from the layout selector. After you select to view a CI topology in the layer layout, you can use most of the options that are available with the other three layouts in Top View (hierarchic, circular, or organic). However, because in the layer layout CIs are divided into functional layers (for example, Business Enablement, Infrastructure, or Software), you cannot use the options such as Show subtree only and Expand to problem.

By using the layer layout, you can see the direction of a CI relationship and the relationship type that links two CIs (visible straightaway if the Show edge label option is enabled, or by hovering over a CI relationship if this option is disabled).

For a better overview, each functional layer is color-coded according to the current worst operational status of a CI in that layer.

The order of layers and the number of CIs displayed in the layer layout can be customized through the Infrastructure Settings. For details, see How to Customize Top View.

The default refresh rate for Top View is five seconds.

You cannot modify refresh rates of the out-of-the-box pages. However, you can create a user-defined page with the components you need, and modify their refresh rates as follows:

1. From the Component Menu drop-down list, select Preferences. The Top View Preferences window opens.
2. Modify the refresh rate as needed, and then click OK.

To change the appearance of the Top View component and use the dark theme, follow these steps:

1. From the Component Menu drop-down list, select Preferences. The Top View Preferences window opens.
2. Select the Use Dark Theme check box, and then click OK.

The following options are available in the Top View toolbar:

UI Element	Description
<View Selector>	Select a view from the drop-down list (on the top left area of the toolbar) to display its CIs.
<Search Bar>	Click to expand, and then type a CI name to focus on that CI.
<Layout Selector>	The hierarchic layout is the default. However, if you choose a different layout for the selected view, the layout preference is saved (every time you select this view, it is displayed in the layout that you chose last). Select one of the following layouts for viewing a CI topology: Hierarchic Layout. This is the default layout. Circular Layout. Organic Layout. The organic layout may require more time to render large topologies compared to the other three layout types. Layer Layout. In this layout, CIs with multiple relationships are displayed only once, with no duplicates. Note If you choose the layer layout, you cannot use all the options that are available with the other three layouts (for example, Show subtree only and Expand to problem).
	Options. Click to access all commonly performed operations when viewing essential applications and business processes: RELOAD. Click to restore the view to its original display. ZOOM TO FIT. Click to automatically resize the CI topology to fit the screen size. EXPORT. Click to export a CI topology as a graph. After you click this button, a new tab opens showing you the image. Right-click the image and save it to the desired location. Note The export format of the image is SVG for Firefox and Safari, and PNG for Internet Explorer. ZOOM. Use the slider to increase or decrease the CI topology display size. DISPLAY OPTIONS. Show KPIs. Use the switch to show or hide KPI icons on CIs. To view a list of CI's KPIs and their statuses, either click the KPI icon or select Open CI Context > KPIs on a CI. Show KPIs with normal status. Use the switch to show or hide KPIs that have the normal status. Show Health Indicators. Use the switch to show or hide Health Indicator icons on CIs. To view HI details, either click or select Open CI Context > Show HIs on a CI. Play sound notification. Use the switch to turn the sound notification option on or off. If this option is turned on, a sound alert is played when a CI in the view changes its status to critical (red). Show edge label. Available only with the layer layout. Use the switch to show or hide the names of the relationships that link CIs in a CI topology. Show multiline labels. Use the switch to enable or disable the display of multiple lines for CIs with long names.

To open the CI context menu, either right-click the selected CI, or hover over the selected CI and then click the Open CI Context button that appears on the right. In the CI context menu, you can choose among the following sections:

• Button actions:

  UI Element	Description
  	Show subtree only. Click to focus only on a particular part of a CI topology.
  	Show Path to Root. Click to display the path from the selected CI to the view root CI. Note To view the path from the selected CI to the view root CI in a separate window, press and hold the Ctrl button and click the Show Path to Root button. Alternatively, you can right-click the selected CI, and then select Show > Path to Root.
  	Show Problematic Subtree. Click to display all child CIs of a problematic CI that have the Critical or Major status. This helps you to quickly locate a problematic child CI that caused the selected parent CI to have a status other than OK. If you want to see a problematic path in isolation, you can use the Show subtree only button. Note To view all child CIs of a problematic CI that have the Critical or Major status in a separate window, press and hold the Ctrl button and click the Show Problematic Subtree button.
