receiver/jaeger: translation of Jaeger agent tags are lost

[flands]

Configure an application to send Jaeger to the Jaeger agent. Configure the Jaeger agent to add tags to the data it is sending out. Configure the Jaeger agent to send tchannel to the OC collector. Have the OC collector export in OC to a backend.

Expected: Jaeger agent tags are seen on spans

Actual: Jaeger agent tags are NOT seen on spans.

@flands per jaegertracing/jaeger#833 (comment) Jaeger agent is only capable to add tags to gRPC. It seems the case that you described.

[pjanotti]

Can you try the same against OpenTelemetry service that has a Jaeger gRPC receiver?

I opened census-instrumentation/opencensus-java#1959 but was closed as a duplicate of this one.

But I am not completely sure what the recommendation is.

I have jaeger traces -> OpenCensus Agent -> OpenCensus Collector -> Stackdriver and looks like the (application) tags and metadata gets dropped or at least I do not see them in Stackdriver console.

Would the Stackdriver exporter export tags and metadata from jaeger traces? Or are they getting dropped even before Stackdriver exporter?

I had

ocagent:

    receivers:
        jaeger:
            collector_http_port: {{ .Values.jaeger_thrift_http_port }}

occollector:

    receivers:
        jaeger:
            jaeger-thrift-http-port: {{ .Values.jaeger_thrift_http_port }}

But the ocagent was sending to occollector via opencensus receiver

 exporters:
        opencensus:
            endpoint: "{{ include "opencensus-service.fullname" . }}-collector:{{ .Values.opencensus_port }}"

I tried changing to

ocagent:

    receivers:
        jaeger:
            collector_http_port: {{ .Values.jaeger_thrift_http_port }}

occollector:

    receivers:
        jaeger:
            jaeger-thrift-tchannel-port: {{ .Values.jaeger_thrift_tchannel_port }}

And the ocagent sending to occollector via jaeger receiver

 exporters:
        opencensus:
            endpoint: "{{ include "opencensus-service.fullname" . }}-collector:{{ .Values.jaeger_thrift_tchannel_port }}"

Now I do not get the traces from occollector sent to stackdriver any more
