Const ExperimentalThis metric defines successful operations using the full success definitions for http
and grpc. Anything else is defined as an unsuccessful operation. For successful
operations, error.type MUST NOT be set. For unsuccessful export operations, error.type MUST contain a relevant failure cause.
If the exporter retries failed export attempts, exactly one observation MUST be recorded per export operation,
covering the wall-clock duration from the start of the first attempt through the conclusion of the final attempt (including any backoff between attempts).
error.type reflects the cause of the final attempt.
This metric is experimental and is subject to breaking changes in minor releases of @opentelemetry/semantic-conventions.
The duration of exporting a batch of telemetry records.
