Defining instance group thresholds for a class

When you right-click an instance in BMC Atrium Explorer, you can select Expand Children or Expand Parents to view the Configuration Items (CIs) related to the selected CI. By default, if four or more instances of a class are related to the CI, the related CIs appear as an instance group to conserve space in the display pane.

For more information about viewing instance groups in BMC Atrium Explorer when you work with related CIs, see Instance groups.

To change the default number of CIs that cause an instance group to appear for a CI class, create an instance of BMC_UIComponent for that CI class. If you specify an instance group threshold for a superclass, the threshold applies to all subclasses that do not also have a threshold specified in a BMC_UIComponent instance. For example, if you specify an instance group threshold of 10 for the BMC_ComputerSystem class, that threshold also applies to the BMC_Mainframe class unless you specify a different threshold value for mainframe CIs.

To define instance group thresholds

  1. Use the following direct access URL to open the BMC_UIComponent form:
  2. Create or modify an instance of BMC_UIComponent, entering values for the following attributes:
    • ClassId — Type BMC_UICOMPONENT.
    • ComponentLocale — The locale for which this threshold is applied. When a client requests under a locale for which there is no threshold defined, the en_US threshold is used.
    • CMDBRowLevelSecurity — Select the Public group.
    • ComponentString — The minimum number of CIs of this class that form an BMC Atrium Explorer instance group.
    • ComponentType — Select ExplorerGroupThreshold.
    • ComponentRelatedClassId — The ID of the class to which this threshold applies. The class ID is case sensitive, and might not be the same as the class name. For example, the class with a name of BMC_ComputerSystem has a class ID of BMC_COMPUTERSYSTEM. For more information about the class ID of a specific class, see the BMC Atrium CMDB Data Model Help.
      Modify the instance with a ComponentRelatedClassId of BMC_ASSETBASE to apply the instance group threshold to all classes in the Common Data Model.
  3. Save your changes.
    New and changed instance group thresholds are available to BMC Atrium Explorer within ten minutes. To make them available sooner, restart the mid tier. After waiting ten minutes or restarting the mid tier, reopen BMC Atrium Explorer.
