When enabled GField will record the field values before and after they are changed. Each parameter will be recorded as its ToString() representation if overridden (and for struct and enum types). If ToString() is not overridden in a class type (or if LogValueDetails is disabled) the base implementation will be replaced with the type's full name and the hash code for that instance. Some implementations of ToString() can produce very long strings and can result in very large messages for certain objects if such details are also enabled (which is the default).
When disabled, only the sampled metric will be recorded, no log messages will be.
