cmd/agent: opencensus receiver w/ jaeger|zipkin exporters no traces

I tried routing traces through the Agent to Zipkin. When it didn't (appear) to work, I added Jaeger. Neither appear to work. I think I'm missing something obvious :-(

ocagent.yaml

YAML
receivers:
  opencensus:
    address: ":55678"

exporters:
  jaeger:
    collector_endpoint: "jaeger:14268/api/traces"
  prometheus:
    address: ":9100"
  zipkin:
    endpoint: "zipkin:9411/api/v2/spans"

zpages:
    port: 9999

and a subset of docker-compose.yaml:

YAML
  opencensus-agent:
    image: omnition/opencensus-agent:0.1.8
    command:
    - --config=/configs/ocagent.yaml
    volumes:
    - "${PWD}/ocagent.yaml:/configs/ocagent.yaml"
    expose:
    - "9100"
    - "9999"
    - "55678"
    ports:
    - 9100:9100
    - 9999:9999

  jaeger:
    image: jaegertracing/all-in-one:1.13
    expose:
    - "14268"
    - "16686"
    ports:
    - 14268:14268
    - 16686:16686

  zipkin:
    image: openzipkin/zipkin
    container_name: zipkin
    expose:
    - "9411"
    ports:
      - 9411:9411

Here's the /tracez for one of the service's exporting to the Agent: image

These traces don't appear to be reflected in the Agent's /tracez. So that's one problem. The Agent is generating its own gRPCs though so I would expect to at least see these:

image

Jaeger is reporting data but it appears to be reporting just traces of its own services: image

Zipkin shows nothing: image

The logs show nothing obvious: Jaeger:

    I ran into the same problem when I tried using the agent to send to jaeger . If this is not going to be addressed in OpenCensus Service, is there a work around?

    I get a similar error here where my traces don't send, but instead some internal agent traces are generated. I am running the example/main.go

    I am trying to incorporate an exporter I created for Azure Monitor to be used in the OpenCensus agent for my internship project. I don't think the error is comming from my exporter code.

    Result on Azure Monitor: image

    What my exporter is exporting on ExportSpan, but they don't all apear on Azure Monitor image

    these spans that you see seem like the ones generated for z-pages by gRPC. The issue mentioned above is a inconsistency for the Jaeger exporter if it applies to your exporter is not clear. Perhaps if you can share your code we can take a look to see if that is the case or not.

    Sorry for the late reply, and thank you for your offer. I was able to find my error to eliminate these extra spans. I accidentally registered my custom exporter right after creating it when the OC agent exporter already registered it. By having only the OC agent register, I eliminated this problem.

    I know it's a very old issue. Curious, did you manage to make Azure exporter work? Do you plan to merge it?

    I tried shipping traces to Jaeger directly and also did not appear to receive traces in Jaeger.

    So, it's probably not the OpenCensus Agent but my code and|or the Jaeger Exporter.

    I'm going to try another configuration.

    I was able to ship traces to Jaeger directly using a mash-up of OpenCensus documentation:

    This E2E example for tracing with Zipking: https://opencensus.io/quickstart/go/tracing/

    With this -- insuffiicient (!?) -- Jaeger example: https://opencensus.io/exporters/supported-exporters/go/jaeger/

    I remain unable to export traces using ocgrpc. Evidently it's something I'm not doing but it remains unclear to me what I'm doing incorrectly and why this doesn't work.

    Note 1

    One additional "Aha!" is that the Jaeger configuration is inconsistent and must be configured as such. Evidently the protocol (http) is required for the collector but not the agent:

    Golang
    agentEndpointURI := "localhost:6831"
    collectorEndpointURI := "http://localhost:14268/api/traces"
    

    Note 2

    Curiously, the Agent's configuration for Jaeger uses only the collectorEndpointURI so -- if the Jaeger Agent endpoint (6831) is required by the Jaeger Exporter it's unclear how this works when its used by the OpenCensus Agent:

    https://github.com/census-instrumentation/opencensus-service#exporters

    YAML
      jaeger:
        collector_endpoint: "http://127.0.0.1:14268/api/traces"

    nice find -- yes the agent/collector configuration is known to be inconsistent. This will be addressed in the OpenTelemetry Service.
