If I understand your question correctly you would like to be able to display the status of a UnDP value on your map in network atlas. We don't currently provide that functionality.
What you may wish to try if you have Application Performance Monitor running is to monitor the OID with the new SNMP OID Monitor component. This component supports collecting a numerical value for which a threshold can be defined.
You can then include the component in your map view using network atlas.
Hope that helps!
