Multiple instances of the same class are grouped in BMC Atrium Explorer and are represented as either a folder icon for configuration items (CIs) or a circle icon (for federated instances). A number above the folder icon indicates the number of instances in the group.
Select and then pause your mouse pointer on a group icon to display the name of the class and the number of instances in the group.
Right-click a group and select an option to display all items in the group or select items from the group. You can show specific items by choosing Select Items to Show and clicking the appropriate check boxes in the Select to Show dialog box.
By default, an instance group appears in BMC Atrium Explorer when four or more instances of a class are related to a CI. BMC Atrium Configuration Management Database (BMC Atrium CMDB) administrators can change the default number of instances that form an instance group. For more information about changing the instance group threshold, see Defining instance group thresholds for a class.
