I'm looking to write an AF DataReference to get MDB Attribute/property information. The information I'm looking to get would be ICU created information about the Interfaces on each machine (point source, UFO_ID, .. not replicated to AF as it is under the %OSI path.) . Was wondering if there was a better way to get this other than a data reference assembly? The AF application I'm creating is a PI system health monitor with Element Relative displays and notifications for problems.
