This article provides brief information when no relations are shown in the AppStack resource on the Group Details view.
All SAM versions
If you have created a group that contains only objects which have no representation within the AppStack environment, for example, Nodes that are switches, routers, wireless access points, interfaces, etc. then they will not have relationships and the only item displayed within the AppStack resource on the Group Details view is the group itself. This is normal behavior. Servers and virtual servers are the only node types that are represented within the AppStack environment. Groups made up of other object types which are not supported by the AppStack environment will not appear within the AppStack resource.
