Adding OID to PDU Device


We are trying to add an OID to a PDU device that will show us status of PDU power ports(plugs). We were hoping the OID would give us a widget in the display of the PDU node, showing status of each power port. 

From the node I clicked on the "Mib Browser". From there, I put the specific OID from APC for power plugs into the search field and the OID comes up. I can tick the box next to the OID, but how then do I add this OID to the node and have it show me the output I'm looking for?

Thank you, Pat
