This string holds the fully qualified Distinguished Name (Dn) that UCS Manager's information model uses as the unique address of this flow-monitoring record definition. Because this flow-monitoring record definition is a NetFlow-style flow-record definition that tells UCS Manager which packet fields to capture for each traffic flow under a flow-monitoring policy, its Dn is what scripts, XML-API calls, and cross-referencing objects (like another object's peerDn field) use to point straight at this exact instance rather than at a plain, possibly duplicated name. A value for this flow-monitoring record definition might look like 'monitor-fmdef-default', with the exact segments reflecting where it sits under the fabric interconnect in the object tree.
