Attempt to use otel-collector

[gianarb]

Hello my application successfully writes traces in the stdout but I decided to try the recently merged PR #497 but I can't get it working:

				logger.Info("Used the tracer output otel-collector")
				exp, err := otlp.NewExporter(otlp.WithInsecure())
				if err != nil {
					log.Fatalf("Failed to create the collector exporter: %v", err)
				}
				defer func() {
					_ = exp.Stop()
				}()

				tp, _ := sdktrace.NewProvider(
					sdktrace.WithConfig(sdktrace.Config{DefaultSampler: sdktrace.AlwaysSample()}),
					sdktrace.WithBatcher(exp, // add following two options to ensure flush
						sdktrace.WithScheduleDelayMillis(5),
						sdktrace.WithMaxExportBatchSize(10),
					))
				if err != nil {
					log.Fatalf("error creating trace provider: %v\n", err)
				}

				global.SetTraceProvider(tp)

I cloned the collector and I am using this configuration:

receivers:
  opencensus:
    endpoint: 0.0.0.0:55678
processors:
  batch:
  queued_retry:
exporters:
  logging:
    loglevel: debug
  jaeger_grpc:
    endpoint: "http://localhost:14250"
service:
  pipelines:
    traces:
      receivers: [opencensus]
      processors: [batch, queued_retry]
      exporters: [jaeger_grpc, logging]

But I do not see any log in the collector, and nothing in jaeger. I don't know what to look at at this point

any pointer?

I was reading around and if I am well reading this PR

open-telemetry/opentelemetry-collector#574 (comment)

The opentelemetry proto receiver does not exist yet. So I presume I have to change receiver and tracer to something that is not opentelemetry grpc but to jaeger

Ok after a chat on Gitter I am right, at the moment there is not otel collector receiver for the grpc protocol, so at the moment it can not be used.

my plan for now is to switch to Jaeger tracer for the project I am working

@gianarb okay to close this?
