Thanks for raising the issue. Since method
and status
are not necessarily specific to HTTP, there should probably be some additional logic to ensure the translation only happens on HTTP spans. Would anyone be willing to submit a pull request?
I opened #229 for this.
Describe the Bug
Since Spring 6 (Spring Boot 3), it is using micrometer-observation and own classes for Observation (Tracing). In those versions the names of tags are changed.
E.g. There are labels "method" and "status": https://github.com/spring-projects/spring-framework/blob/main/spring-web/src/main/java/org/springframework/http/server/observation/ServerHttpObservationDocumentation.java#L61-L77
In Spring 5 with Sleuth/OpenTracing there were "http.method" and "http.status_code" labels: https://github.com/opentracing/opentracing-java/blob/master/opentracing-api/src/main/java/io/opentracing/tag/Tags.java#L56-L61
Zipkin-gcp provides SpanTranslator to translate those names to GCP Tracing convention: https://github.com/openzipkin/zipkin-gcp/blob/master/translation-stackdriver/src/main/java/zipkin2/translation/stackdriver/SpanTranslator.java#L27-L36
Unfortunately, it works correctly only with Spring 5 (Spring Boot 2.X) and does not translate new labels.
The result is that after updating to Spring 6 the status code and method are treated as custom labels and are not assigned to special fields "Status" and "Method" e.g. their values are no longer visible in the summary table.
Expected Behaviour
SpanTranslator should translate new labels names from Spring 6.
