This is the Relative Name (RN) of an admin-defined destination (server, protocol, and path) for manually pushing a captured core (crash) file off the fabric interconnect, the naming component that distinguishes this particular instance from its sibling instances under the same parent object. Because UCS can have many instances of the same class nested under a parent, the RN is what lets UCS Manager and SNMP tools tell them apart without needing the full DN. For example, an admin sending a process crash dump to an external server so Cisco TAC can analyze it, and the RN is the short label that identifies this one instance among its siblings.
