This is the Relative Name (RN) of a 64-bit threshold definition object: the single naming component that, combined with its parent's DN, distinguishes this 64-bit threshold definition from any sibling instances under the same parent. Admins rarely read the RN by itself, but UCS Manager and management tools use it to build and parse the full DN path so each instance of the definition of one 64-bit-valued statistics threshold, used for larger cumulative counters such as total bytes transferred, that belongs to a threshold policy can be addressed uniquely. For instance, when a threshold policy has several 64-bit threshold definitions attached, the RN is the piece that differs between their otherwise-identical parent DNs, letting a script enumerate all of them.
