About OpsCenter view levels
A newly created view has only one level. You can add multiple nodes to a view at different levels. You can add alias for each of these view levels.
Only a Security Administrator or an Administrator can modify views.
See Modifying alias view levels in OpsCenter.
Primary server hosts, clients, or policies are always at the lowest levels in a view. Between the top level and the bottom level, you can create multiple intermediate levels to organize view objects into logical groups, creating a hierarchical structure in the view.
