Usage

The extension automatically creates a Camel OpenTracingTracer and binds it to the Camel registry.

In order to send the captured traces to a tracing system, you need to configure some properties within application.properties like those below.

quarkus.jaeger.service-name=my-service
quarkus.jaeger.sampler-type=const
quarkus.jaeger.sampler-param=1
quarkus.jaeger.endpoint=http://localhost:14268/api/traces

Refer to the Quarkus OpenTracing guide for a full list of configuration options.

Route endpoints can be excluded from tracing by configuring a property named quarkus.camel.opentracing.exclude-patterns in application.properties. For example:

# Exclude all direct & netty-http endpoints from tracing
quarkus.camel.opentracing.exclude-patterns=direct:*,netty-http:*
