Hi,
The color of the link is not changing "Yellow" to show the warning status. However it goes red when the connectivity fail.
Can you check the configuration ?
What Configuration ??. Please explain.
The configuration of the alert.Or script that you use to change the color.
If you looking for the map to display a 'weather map' like the one below
http://oriondemo.solarwinds.com/Orion/NetPerfMon/MapView.aspx?Map=587f1504-2d2f-4524-931c-bd3e31ca40e9.OrionMap&Title=Africa
Edit the map from the 'Network Atlas' utility and from the 'More Options' on the bottom left hand, choose 'show link utilization' option and save the map
Otherwise, the link doesn't change color based on utilization levels.
