Package io.quarkus.opentelemetry.runtime.tracing.intrumentation.reactivemessaging

Class ReactiveMessagingTracingDecorator

  • All Implemented Interfaces:
    io.smallrye.reactive.messaging.PublisherDecorator, io.smallrye.reactive.messaging.SubscriberDecorator, jakarta.enterprise.inject.spi.Prioritized
    @ApplicationScoped
public class ReactiveMessagingTracingDecorator
extends Object
implements io.smallrye.reactive.messaging.PublisherDecorator, io.smallrye.reactive.messaging.SubscriberDecorator
    Intercepts incoming and outgoing messages from Reactive Messaging connectors.

    For incoming messages, it fetches OpenTelemetry context from the message and attaches to the duplicated context of the message. Consumer methods will be called on this duplicated context, so the OpenTelemetry context associated with the incoming message will be propagated.

    For outgoing messages, if the message doesn't already contain a tracing metadata, it attaches one with the current OpenTelemetry context. Reactive messaging outbound connectors, if tracing is supported, will use that context as parent span to trace outbound message transmission.
