This is the Relative Name (RN) of a floating-point threshold definition object: the single naming component that, combined with its parent's DN, distinguishes this floating-point 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 floating-point statistics threshold, used for readings such as temperature, voltage, or fan speed, that belongs to a threshold policy can be addressed uniquely. For instance, when a threshold policy has several floating-point threshold definitions attached, the RN is the piece that differs between their otherwise-identical parent DNs, letting a script enumerate all of them.
