Details

Usually you do not need to deal with otel_up_down_counter objects directly. up_down_counter_add() automatically sets up a meter and creates an up-down counter instrument, as needed.

An up-down counter object is created by calling the create_up_down_counter() method of an otel_meter_provider().

You can use the add() method to increment or decrement the counter.

In R up-down counters are represented by double values.
