kubernetes - Tracing Apache Camel route with Jaeger

Question

I have developed a Camel route with Spring Boot. Now I want to trace the route using Jaeger. I tried this example to trace the route using camel-opentracing component, but I am unable to get the traces to Jaeger.

I can only see it in the console. One thing I am not clear is where to add the Jaeger URL? Any working example will be helpful.

Answer 1

What I eventually did is create a JaegerTraces and annotated with Bean

Answer 2

Apache Camel doesn't provide an implementation of OpenTracing, so you have to add also an implementation to your dependencies. For example Jaeger.

Maven POM:

    <dependency>
        <groupId>org.apache.camel.springboot</groupId>
        <artifactId>camel-opentracing-starter</artifactId>
        <version>${camel.version}</version>
    </dependency>
    <dependency>
        <groupId>io.opentracing.contrib</groupId>
        <artifactId>opentracing-spring-jaeger-starter</artifactId>
        <version>3.2.2</version>
    </dependency>

Also you have to enable OpenTracing for Apache Camel on your Spring Boot application class, see Spring Boot:

If you are using Spring Boot then you can add the camel-opentracing-starter dependency, and turn on OpenTracing by annotating the main class with @CamelOpenTracing.

The Tracer will be implicitly obtained from the camel context’s Registry, or the ServiceLoader, unless a Tracer bean has been defined by the application.

Spring Boot application class:

@SpringBootApplication
@CamelOpenTracing
public class CamelApplication {

    public static void main(String[] args) {
        SpringApplication.run(CamelApplication.class, args);
    }
}
