I am using Zuul as an api-gateway in a spring-cloud micro-service app, so that every access to api-gateway/some-service/a_route is redirected to /a_route in a generic way (the discovery is backed by consul).
I am trying to use Jaeger to instrument this system. And at this point I am using opentracing-spring-web-autoconfigure, because I cannot upgrade my spring boot/cloud version easily (I am using1.4.5.RELEASE Camden.SR7). So I just added the dependency, created the Jaeger tracer and redirect it to the docker all in one collector.
I have begin by instrumenting the gateway and It somewhat works => It generate span on the gateway, but all the route are marked :
apigateway-service: GET
and there is no information concerning the forwarded route at this level, the full route itself is store in a tag : http.url
"http://localhost:8080/collection-service/collections/projects/"
To be useful I would prefer to have span named :
apigateway-service: GET collection-service/collections/projects/
Can this be configured somewhere ?
No, it cannot, but it wouldn't hurt to open an issue there with this suggestion.
