rpc error: code = Unimplemented desc = unknown service

follow OpenTelemetry Collector Traces Example，but I am using binary.

The operation is as follows:

git clone [email protected]:open-telemetry/opentelemetry-go-contrib.git
make otelcontribcol

cd  ~/opentelemetry-collector/bin

./otelcontribcol --config /root/opentelemetry-config/demo-config.yaml

demo-config.yaml is

receivers:
  otlp:
    protocols:
      grpc:
        endpoint: "0.0.0.0:4317"

processors:

exporters:
  prometheusremotewrite:
    endpoint: "http://192.168.1.20:30566/api/v1/write"

service:
  pipelines:
    metrics:
      receivers: [otlp]
      processors: []
      exporters: [prometheusremotewrite]

git clone [email protected]:open-telemetry/opentelemetry-go.git

cd  ~/opentelemetry-go/example/otel-collector

go run main.go

tutorial use image: otel/opentelemetry-collector:0.6.0

I don't know version of the binary.

Could anyone do me a favor? thanks.

1. Your collector configuration is suited for metrics - not traces. The example is made for traces.
2. I do not believe otel/opentelemetry-collector:0.6.0 was supporting metrics - however, I have not checked it. Try using something newer.

@william-lbn can you confirm this is still an issue for you?

[MrAlias]

Closing as this looks stale. Please re-open if this was an error.

failed to upload metrics: rpc error: code = Unimplemented desc = unknown service opentelemetry.proto.collector.metrics.v1.MetricsService I am getting this error while using grpc endpoint to send metric data to otel collector I am using otel collector otelcol: image: otel/opentelemetry-collector-contrib:0.76.1

Not sure if this helps, I was also facing this issue, and turned out that I haven't configured the service.pipelines.metrics. So after I've added the following, it no longer complained:

The docker image I'm using is:

ghcr.io/open-telemetry/opentelemetry-collector-releases/opentelemetry-collector:0.89.0

It's the otc-container being injected by the opentelemetry-operator helm chart. Installation instructions here: https://operatorhub.io/operator/opentelemetry-operator
