Exporters

In order to visualize and analyze your traces and metrics, you will need to export them to a backend.

OTLP endpoint

To send trace data to an OTLP endpoint (like the collector or Jaeger >= v1.35.0) you'll want to configure an OTLP exporter that sends to your endpoint.

Using HTTP

    "go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp"
)

func installExportPipeline(ctx context.Context) (func(context.Context) error, error) {
    client := otlptracehttp.NewClient()
    exporter, err := otlptrace.New(ctx, client)
    if err != nil {
        return nil, fmt.Errorf("creating OTLP trace exporter: %w", err)
    }
    /* … */
}

Jaeger

To try out the OTLP exporter, since v1.35.0 you can run Jaeger as an OTLP endpoint and for trace visualization in a docker container:

Prometheus

Prometheus export is available in the go.opentelemetry.io/otel/exporters/prometheus package.
