This observer MUST be registered when creating a batchCallback, which records to it. Values observed outside registered callbacks are ignored.

Specified by:

buildObserver in interface DoubleUpDownCounterBuilder

Returns:

an observable measurement that batch callbacks use to observe values.

setAttributesAdvice
