Cannot see the Launch Relationship Viewer from the Actions menu appear for the USM groups
The Launch Relationship Viewer menu option is present only if the relationship_services probe is running and at least one relationship exists for the selected group or group member.
If you first select a group or specific managed element, the Relationship Viewer opens with the selected element(s) centered and with the radius slider visible. If you do not make such a selection first, the Relationship Viewer opens with all managed elements visible at the lowest zoom level.
If multiple relationships are available, a sub-menu of your choices is displayed when you click Launch Relationship Viewer; click your preference to open the Relationship
Viewer using that relationship.
