Implementing Distributed Tracing With Jaeger

1. Add the OpenTracing extension:

   ./mvnw quarkus:add-extensions -Dextensions=quarkus-smallrye-opentracing

2. Add the configuration to application.properties

   quarkus.jaeger.service-name=todoservice
   quarkus.jaeger.sampler-type=const       ## Sampling type
   quarkus.jaeger.sampler-param=5          ## Sampling rate, in this case every fifth request is sampled
   quarkus.log.console.format=%d{HH:mm:ss} %-5p traceId=%X{traceId}, parentId=%X{parentId}, spanId=%X{spanId}, sampled=%X{sampled} [%c{2.}] (%t) %s%e%n
   # quarkus.jaeger.endpoint=http://jaeger-collector:12345/api/traces

   • This will result in all REST requests having tracing implemented
3. Addition tracing extensions for JDBC, Kafka, and MongoDB are also availabe and you can find documentation HERE
