About this task

In order for a CI to be considered an orphan CI, specify attributes that a CI must have, relationships that a CI should not have, or both. In the relationship conditions, you can either specify that the CI has no relationships, or a set of specific relationships that he CI does not have. An orphan rule can for example define that if a CI doesn’t have an owner or an asset, then it is considered an orphan CI.


  1. Navigate to Configuration > CI Class Manager.
  2. Select a class from the Class Hierarchy.
  3. On the right-hand side navigation pane, check Advanced, expand the Correctness strip, and click Orphan Rule.
  4. If an orphan rule exists for the selected class, double-click it to edit, or click New.
  5. Complete or edit the form.
    Table 1. CMDB Health Orphan Rule form
    Field Description
    Class The class for which the orphan rule applies.
    Attributes Attribute conditions that a CI must satisfy to be considered an orphan CI. For example, the filter conditions in which both the Assigned to and the Owned by fields are empty, will identify the matching CIs as orphans.

    Relationship The relationship conditions that a CI must fail in order to be considered an orphan CI.
