| = OpenTracing Extension |
| |
| *Available as of Camel Quarkus version 0.21* |
| |
| The OpenTracing extension is used for tracing and timing incoming and outgoing Camel messages. |
| |
| Maven users will need to add the following dependency to their `pom.xml` for this extension. |
| |
| [source,xml] |
| ------------------------------------------------------------ |
| <dependency> |
| <groupId>org.apache.camel.quarkus</groupId> |
| <artifactId>camel-quarkus-opentracing</artifactId> |
| </dependency> |

| |
| == 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 https://quarkus.io/guides/opentracing-guide#configuration-reference[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:* |
| .... |
| |
