The instance namer overrides how the object containing the field is identified.
Since the GField attribute is applied to a field it will be tracked for all instances of the related class. With the exception of static classes this may be a potentially unbounded set of different objects. By default, every object has a unique runtime identifier which is recorded with the metric value to enable correlation during analysis but this value is not predictable or consistent. Instead, if an object has a property that represents a more useful, unique name for the object then specifying its name in this property will produce more useful log messages and graphs.
