Chapter 8. Logging and tracing

Procedure

1. Add the Jaeger client dependency to your POM file.

   <dependency>
     <groupId>io.jaegertracing</groupId>
     <artifactId>jaeger-client</artifactId>
     <version>${jaeger-version}</version>
   </dependency>

   ${jaeger-version} must be 1.0.0 or later.

2. Add the jms.tracing option to your connection URI. Set the value to opentracing.

   Example: A connection URI with tracing enabled

   amqps://example.net?jms.tracing=opentracing

3. Register the global tracer.

   Example: Global tracer registration

   import io.jaegertracing.Configuration;
   import io.opentracing.Tracer;
   import io.opentracing.util.GlobalTracer;
   
   public class Example {
       public static void main(String[] args) {
           Tracer tracer = Configuration.fromEnv("<service-name>").getTracer();
           GlobalTracer.registerIfAbsent(tracer);
   
           // ...
       }
   }

4. Configure your environment for tracing.

   Example: Tracing configuration

   $ export JAEGER_SAMPLER_TYPE=const
   $ export JAEGER_SAMPLER_PARAM=1
   $ java -jar example.jar net.example.Example

   The configuration shown here is for demonstration purposes. For more information about Jaeger configuration, see Configuration via Environment and Jaeger Sampling.
