Vert.x Kafka Client

OpenTelemetry Java agent instrumentation

This instrumentation enables messaging spans for Kafka consumers using the Vert.x Kafka Client library.

Name: vertx-kafka-client-3.6
Scope: io.opentelemetry.vertx-kafka-client-3.6
Target versions: io.vertx:vertx-kafka-client:[3.5.1,)
Library: https://vertx.io/docs/vertx-kafka-client/java/

Telemetry

Span attributes: messaging.batch.message_count, messaging.client_id, messaging.destination.name, messaging.destination.partition.id, messaging.kafka.message.key, messaging.kafka.message.offset, messaging.message.body.size, messaging.operation, messaging.system, kafka.record.queue_time_ms

Configuration

Option	Type	Default	Description
`otel.instrumentation.messaging.experimental.capture-headers`	list		A comma-separated list of header names to capture as span attributes.
`otel.instrumentation.kafka.experimental-span-attributes`	boolean	false	Enables the capture of the experimental consumer attributes `kafka.record.queue_time_ms` and `messaging.kafka.bootstrap.servers`.
`otel.instrumentation.kafka.producer-propagation.enabled`	boolean	true	Enable context propagation for Kafka message producers.
`otel.instrumentation.messaging.experimental.receive-telemetry.enabled`	boolean	false	Enables experimental receive telemetry, which will cause consumers to start a new trace, with only a span link connecting it to the producer trace.
