Instrumentation.ConfluentKafka-0.2.0-alpha.1

• NuGet: OpenTelemetry.Instrumentation.ConfluentKafka v0.2.0-alpha.1

  • Updated OpenTelemetry core component version(s) to 1.16.0.
    (#4487)

  • Supported manual configuration of traces and metrics for Kafka consumers
    and producers created outside a DI container.
    (#4545)

  • Assemblies are now digitally signed using cosign.
    (#4637)

  • Breaking change: Updated the traces and metrics emitted by the Kafka
    producer and consumer to follow the
    v1.43.0 messaging semantic conventions.
    The producer send span (previously publish) and the consumer poll
    span (previously receive, and now emitted with ActivityKind.Client) now
    set:

    • messaging.operation.name and messaging.operation.type
      (replacing messaging.operation)
    • messaging.client.id (replacing messaging.client_id)
    • messaging.consumer.group.name (replacing
      messaging.kafka.consumer.group)
    • messaging.destination.partition.id (a string) (replacing
      messaging.kafka.destination.partition)
    • messaging.kafka.offset (replacing messaging.kafka.message.offset)

    messaging.kafka.message.key is now emitted as a string when the key has an
    unambiguous canonical representation; otherwise, the attribute is omitted.

    The metrics were renamed to:

    • messaging.client.operation.duration
      (replacing messaging.publish.duration and messaging.receive.duration)
    • messaging.client.sent.messages (replacing messaging.publish.messages)
    • messaging.client.consumed.messages
      (replacing messaging.receive.messages).

    error.type is now reported as the language-agnostic Kafka error code for
    Kafka errors (ProduceException/ConsumeException), or the exception type
    name for other failures (such as an ArgumentException from the producer or
    an exception thrown by a message handler).
    (#4636)

  • Metrics and traces now include a telemetry schema URL.
