Go Tracing + OpenTelemetry

1.go

func producer(ctx context.Context) {
	tr := global.TraceProvider().Tracer("component-producer")
	_, span := tr.Start(ctx, "producer")
	defer span.End()

  	// Get tracing id and Parent span id
  	traceId := fmt.Sprintf("%016x", span.SpanContext().TraceID)
  	spanId := fmt.Sprintf("%016x", span.SpanContext().SpanID)
  
  	// Add to message
 
}

2.go

func consumer(traceID string, spanID string) {
	fn := initTracer("trace-consumer")
	defer fn()

	tid, _ := core.TraceIDFromHex(traceID)
	sid, _ := core.SpanIDFromHex(spanID)

	ctx := context.Background()
	tr := global.TraceProvider().Tracer("consumer-step01")
	sc := core.SpanContext{
		TraceID:    tid,
		SpanID:     sid,
		TraceFlags: 0x0,
	}
	_, span := tr.Start(trace.ContextWithRemoteSpanContext(ctx, sc), "consumer-span1")
	span.End()
}
