4. Click  to configure the sunburst chart. In the edit screen, select one of the following options and configure the properties:

   • Based on System types
   • Based on Data mart

   This mode lets you customize the hierarchy of the data to be displayed (selecting a parent entity and its child entities) based on the system type. You can choose to enable grouping of entities by Domain, Business Service, Organization, or Location Site.

   1. System type: Select the top-level entity to display. This is the parent entity that will contain the rest of the child entities within it. For example, to select child entities as AIX LPAR, Virtual Machine - AIX Shared Processor LPAR, and Virtual Machine - AIX VIO LPAR, you can select System type as Virtual Host - AIX PowerVM.
   2. Related information: Click + Add link to add related links. In the edit box, type a name for the link, select the page you want to link to, and click Apply. 
      The links you add are displayed under Related information. You can edit or delete the available links.
   3. Size: Click + Add metric to select the metric for the capacity size for the selected system. The selected size metric determines the size of the rectangle that represents that entity. 
      The Metrics panel lists all available metrics for the selected system types. The metrics are grouped by category such as CPU, Storage, and Memory. Click a category to expand it and select the metrics. You can also search for a metric. The selected metrics are listed in the Selected Metrics panel. Click Done. 
   4. Utilization: Click + Add metric to select the metric for the utilization of the selected system. This metric determines the color of the rectangle that represents that entity. For example, if you select CPU UTIL, the rectangle representing that entity will be displayed in the color based on how much of the entity is utilized, or free.
      
      The Metrics panel lists all configuration and performance metrics for the selected system types. The metrics are grouped by category such as CPU, Storage, Memory, and By Disk. Click a category to expand it and select the metrics. You can also search for a metric. The selected metrics are listed in the Selected Metrics panel. Click Done. 
      It is recommended that you select two distinct metrics for Size and Utilization.
      The metric listed in the Metrics panel are rolling statistics. You can select out-of-the-box and custom rolling statistics for a metric. Ensure that the rolling statistic that you want to add is already created. For more information, see Working-with-custom-statistics.

   5. To add child entities, click + Add system type. You can add several levels of child entities. The entities that are listed in consecutive lists are based on the parent entity you select in the previous step. For example if you select  Virtual Cluster VMware as the parent entity, the following System type list will contain only the children of Virtual Cluster VMware .    

      If there are no child entities available for the entity selected in the previous step, a message is displayed that no child entity is found.
      If you add several levels of child entities, the Size and Utilization metrics selection for the previous child entity is cleared, and you must select the metrics again for the new child entity. These metrics for the child entity level are summarized at the parent entity level.

   This mode lets you customize the hierarchy of the data to be displayed (selecting a parent entity and its child entities) based on the custom data mart.

   1. Data mart: Select the data mart from the list that contains the required data to be displayed in the map. The options in the subsequent fields are displayed according to the data mart selected.
   2. Level 1: Select the column that represents top-level entity to display. This is the parent entity that will contain the rest of the child entities within it. This field displays the columns with name or ID values.
   3. Related information: Click + Add link to add related links. In the edit box, type a name for the link, select the page you want to link to, and click Apply. 
      The links you add are displayed under Related information. You can edit or delete the available links.
   4. Size: Select the column to identify the size of the selected level 1 column. The size column determines the size of the rectangle that represents the level 1 entity. 
   5. Utilization: Select the column to identify the utilization of the selected level 1 column. The utilization column determines the color of the rectangle that represents the level 1 entity.

   6. To add further levels, click + Add level. You can add several levels depending on the selected data mart.

      If you add several levels, the Size and Utilization column selection for the previous level is cleared, and you must select the size and utilization columns again for the new level. These columns for the child level are summarized at the parent level.

To read the Sunburst chart

After you create a custom view page with the Sunburst template, the innermost circle in the Sunburst represents the root entity, with the hierarchy moving outward from the center node as shown in the following image:

The size of the nodes denotes the capacity size on that entity.

The color of the nodes denotes the usage percentage of that entity, with white indicating no usage and red indicating high usage.

To view details of the node

When you hover over a particular node, the following details are displayed: 

• The hierarchy for that node is listed at the the top-left of the Sunburst.
• A Details tooltip opens. It lists the Name, Type, Utilization (%) and Size of the node. When you click on the tooltip, this tooltip is replaced by a popup window with the additional information displayed as Related link.
• The chart at the right of the Sunburst displays the data according to the configured metrics.

Similarly, you can view the details of each child entity within a parent entity.

To view a particular entity and navigate back to the parent entity

You can focus only on a particular entity at a time and not display the others. To do this, double-click that entity. The entity is displayed as the root entity.

If the entity does not have any child entities, only the selected entity is displayed.

If the entity has child entities, the selected entity and the child entities are displayed.

To navigate back to the parent entity, double-click the center. 

To change the Sunburst layout

By default, the Sunburst chart displays the entities by their size and utilization. To view the entities only by capacity size, you must change the layout. 

In the Sunburst view, click  next to Layout by Size/Utilization and click Layout by Size. The Sunburst chart displays the entities by capacity size, with each parent node displayed in the different color and respective child nodes in different shades of that color. The innermost node is displayed in the white color.

To use time filters in the Sunburst view

You can view data for predefined time periods. By default, data for the Last 30 days is shown. To view data for a different time period, use the available time filters.

In the Sunburst view, click the action menu  next to the time filter and select a time period as shown in the following image:

You can select from the following options:

• Yesterday
• Last 7 days
• Last 30 days

Data for the selected time period is displayed.
