Because you cannot change the rules for system-defined groups, Operations Manager provides user-defined groups that can contain the devices, ports, or interfaces in which you are interested. Port and interface containment is only seen and used by Polling and Thresholds (see Configuring Polling and Thresholds), but device groups will contain members when devices are added to the Operations Manager inventory. Once you edit or create a group, you can determine whether other users can view the group.
User-defined groups are the basis for the views that appear in the Monitoring Dashboards (Service Level View, Alerts and Events, Phone Activities, and Service Quality Alerts). For every user-defined group you create, a corresponding view is automatically created. For creating user-defined groups, see Creating and Editing Groups.
