Parent-child relationships normally occur between interrelated objects in your environment. For example, a data center object for a vCenter Adapter instance might have datastore, cluster, and host system child objects.
The most common object relationships gather similar objects into groups. When you define a custom group with parent objects, a summary of that group shows alerts for that object and for any of its descendants. You can create relationships between objects that might not normally be related. For example, you might define a child object for an object in the group. You define these types of relationships by configuring object relationships.
- At the Home page, select Administration. Then select in the left pane.
- In the Parent Selection column, expand the object tag and select a tag value that contains the object to act as the parent object.
The objects for the tag value appear in the top pane of the second column.
- Select a parent object.
Current child objects appear in the bottom pane of the second column.
- In the column to the right of the List column, expand the object tag and select a tag value that contains the child object to relate to the parent.
- (Optional) If the list of objects is long, filter the list to find the child object or objects.
Option Action Navigate the object tag list for an object Expand the object tag in the pane to the right of the List column and select a tag value that contains the object. The objects for the tag value appear in the List column. If you select more than one value for the same tag, the list contains objects that have either value. If you select values for two or more different tags, the list includes only objects that have all of the selected values. Search for an object by name If you know all or part of the object name, enter it in the Search text box and press Enter.
- To make an object a child object of the parent object, select the object from the list and drag it to the parent object in the top pane of the second column, or click the Add All Objects To Parent icon to make all of the listed objects children of the parent object.
You can use Ctrl+click to select multiple objects or Shift+click to select a range of objects.
Example: Custom Group with Child Objects
If you want vRealize Operations Cloud to monitor objects in your environment to ensure that service level capacity requirements for your IT department are met, you add the objects to a custom group, apply a group policy, and define criteria that affect the membership of objects in the group. If you want to monitor the capacity of an object that does not affect the service level requirements, you can add the object as a child of a parent object in the group. If a capacity problem exists for the child object, the summary of the group shows an alert for the parent object.
