The way this is implemented is that you need to have DCIs that do actual traffic information collection. In other options of these DCIs related interface object should be specified and interpretation, e.g. "Interface traffic - Outbound - bytes/sec" should be set.
When adding DCIs from context menu of interface(s), these parameters are set automatically. You can check, if these are set correctly by checking Overview tab of the interface - it should now have "Inbound utilization" and "Outbound utilization" lines.
Currently only Outbound utilization is taken, so a list should have these DCIs on both ends. Color schema is such, that link with 0% traffic is gray, but it should change it's color with traffic.
This is a new feature, so some improvements might be made to make it simpler/more understandable.
