otel.sdk.exporter.operation.duration and otel.sdk.metric_reader.collection.duration omit explicit_bucket_boundaries_advisory=[] #5892

Description

otel.sdk.exporter.operation.duration and otel.sdk.metric_reader.collection.duration are created via create_otel_sdk_exporter_operation_duration and create_otel_sdk_metric_reader_collection_duration without explicit_bucket_boundaries_advisory=[]:

  Line 113 in 66ec883

  self._duration = create_otel_sdk_exporter_operation_duration(meter)

  Line 40 in 66ec883

  self._collection_duration = create_otel_sdk_metric_reader_collection_duration(meter)

  	"""The duration of exporting a batch of telemetry records"""
  	return meter.create_histogram(
  	name=OTEL_SDK_EXPORTER_OPERATION_DURATION,
  	description="The duration of exporting a batch of telemetry records.",
  	unit="s",
  	)

  Lines 220 to 226 in 66ec883

  	def create_otel_sdk_metric_reader_collection_duration(meter: Meter) -> Histogram:
  	"""The duration of the collect operation of the metric reader"""
  	return meter.create_histogram(
  	name=OTEL_SDK_METRIC_READER_COLLECTION_DURATION,
  	description="The duration of the collect operation of the metric reader.",
  	unit="s",
  	)

Per the SDK self-observability specification for otel.sdk.exporter.operation.duration and otel.sdk.metric_reader.collection.duration, both histograms SHOULD be specified with the ExplicitBucketBoundaries advisory parameter with a single bucket with no boundaries (explicit_bucket_boundaries_advisory=[]). Without this advisory, the SDK applies the default millisecond bucket boundaries ((0.0, 5.0, 10.0, ..., 10000.0)) to metrics measured in seconds (s).

Expected behavior

Both otel.sdk.exporter.operation.duration and otel.sdk.metric_reader.collection.duration should pass explicit_bucket_boundaries_advisory=[] to meter.create_histogram().
