  .setTracingOptions(
    new OpenTelemetryOptions()
      .addExporter(JaegerExporter.newBuilder()

How to use Jaeger as backend

Start a Jaeger instance with the following command

docker run -d --name jaeger \
  -e COLLECTOR_ZIPKIN_HTTP_PORT=9411 \
  -p 5775:5775/udp \
  -p 6831:6831/udp \
  -p 6832:6832/udp \
  -p 5778:5778 \
  -p 16686:16686 \
  -p 14268:14268 \
  -p 14254:14254 \
  -p 9411:9411 \
  jaegertracing/all-in-one

The Jaeger UI will be accessible at http://localhost:16686/
