Configuring the Tree Map template

The Tree Map template is a space-filling visualization template that displays data in a hierarchical structure, as a set of nested rectangles. The outer rectangle represents the parent entity and the inner rectangles are the child entities.

To configure a view using the Tree Map template

The following video (9:10) illustrates how to read a tree map and the process of creating a custom view page by using the Tree Map template.

  1. Open the view page with the Tree Map template:

  2. In the edit screen at the bottom, select either the Based on template or Custom edit mode.

    • Based on template:  If you select the  Based on template  mode, configure the following properties:

      1. From the System type list, select the type of entity that you want to display. The tree map displays data of only the selected entity type. For example, Virtual Cluster VMware

      2. From the Template list, select the template, based on which to display the data. The templates available for selection are filtered by the System type selection. That is if you select Virtual Cluster VMware in the Entity type list, the Template list is populated by templates that are applicable only to Virtual Cluster VMware.

        After you select a template, its description is displayed.

        The tree map displays data of the selected entity type, based on the chosen template.

        You can also directly select a template, without selecting an entity. In this case, the tree map displays data of all available entity types. 

    • Custom: The Custom mode lets you customize the hierarchy of the data to display, that is, you can select a parent entity and its child entities. You can also choose to show a flat hierarchy, where no child entities are displayed. To use the Custom mode, perform the following tasks:

      1. From the first System type list, 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 for selecting multiple child entities as AIX LPAR, Virtual Machine - AIX Shared Processor LPAR and Virtual Machine - AIX VIO LPAR, you can select Virtual Host - AIX PowerVM as the first System type.

      2. Click  + Add system type to add a child entity.  

        You can add several levels of child entities. If there are no child entities available, a message is displayed indicating that there are no child entities available.  

      3. Related information: Add a drill-down link to a related page. You can link to another page in a different view.

        1. To add a link, click + Add link.

          To edit an existing link, click Change.

        2. In the Link label box, type a name for the link.

        3. From the Target page list, select the page you want to link to. The corresponding system is displayed in the target page.

        4. Click Done to go back to the previous edit screen.
      4. From the corresponding  Size  list, click + Add metric to select the metric for the capacity size for the selected system.

        The size metric you select, determines the size of the rectangle that represents that entity.

        1. In the Metrics  panel, depending on the system type you select, the Metrics panel lists the configuration metrics for that system type, to choose from.

          The metrics are grouped by category, for example, CPU , Disk , Formulas , Memory , BYFileSystem and so on. Click  to expand the category and select the metrics.

          You can also search for a metric using the box located at  the top of the Metrics panel.

          The selected metric is listed in the Selected metrics panel.

        2. Click Done to go back to the previous edit screen. 

      5. From the corresponding Utilization list, select the metric to represent the selected child entity.

        The utilization metric you select, 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.

        1. In the Metrics  panel, depending on the system type you select, the Metrics panel lists the configuration and performance metrics for that system type, to choose from.

          The metrics are grouped by category, for example, CPU , Disk , Formulas , Memory , BYFileSystem and so on. Click  to expand the category and select the metrics.

          You can also search for a metric using the box located at  the top of the Metrics panel.

          It is recommended that you select two distinct metrics for Size and Utilization. If you select the same metric for both Size and Utilization

          The selected metric is listed in the Selected metrics panel.

        2. Click Done to go back to the previous edit screen.

      6. To display more child entities, click  + Add system type .

        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 .    

        Notes

        • If you add several levels of child entities, the size and utilization metric selection for the previous child entity is cleared, and you must select the metrics again for the new child entity.  
        • If there are no child entities available for the entity selected in the previous step, a message is displayed informing that no child entity is found.

        The Size and Utilization metrics that you select for the child entity level are summarized at the parent entity level.

      7. Click  Done  to go back to the previous screen.

  3. (Optional) To add custom text when you configure a new template or add a new page, click Add custom text.
    To update existing custom text, click Edit the page, and then in the custom text panel, click Change
    For more information, see Managing custom text on a view page.

  4. Click  Apply . The changes are updated dynamically in the view, and you continue to be in the edit mode

    Note

    Clicking Apply displays a dynamic preview of your configuration, without saving the changes. This dynamic update helps you to review your changes, and if required, quickly make further changes as you continue to be in the edit mode.

  5. If you are satisfied with the changes, and do not want to edit the page further, click Save .

    The custom view page is created with the defined configuration.
