Which style map are they using? I know on the Network Atlas when you put your mouse over the pin, it will show what the node/group/application is. I'm not sure about how it works on the World Map.
We use the Global Network Map.
When hovered upon (Red icon/node) it definitely displays what nodes are down. though it takes four clicks to drill down on the same icon to its location until it begins to appear on the right side w/ clickable nodes (down nodes and remaining nodes in that group/icon).
My customers want to be able to click on the icon from the map once followed by a display of clickable nodes on the right side instead of four clicks until they get there. Basically not wanting to drill down.
