OpenTelemetry Exporters

Once the OpenTelemetry SDK has created and processed telemetry, it needs to be exported. This package contains exporters for this purpose.

Exporter Packages

The following exporter packages are provided with the following OpenTelemetry signal support.

OTLP Logs exporter

Regarding specification otlp exporter implemented otlplogsgrpc and otlplogshttp clients with next protocols supported: gprc, http/protobuf and http/json.

If client is not configured explicitly ,The OTEL_EXPORTER_OTLP_PROTOCOL, OTEL_EXPORTER_OTLP_LOGS_PROTOCOL environment variables specify the OTLP transport protocol. Supported values:

• grpc for protobuf-encoded data using gRPC wire format over HTTP/2 connection
• http/protobuf for protobuf-encoded data over HTTP connection
• http/json for JSON-encoded data over HTTP connection

package main

func main() {
	ctx := context.Background()
	exporter, _ := otlplogs.NewExporter(ctx) // will create exporter with http client `http/protobuf` protocol by default

}

OTEL client with grpc

Use OTEL_EXPORTER_OTLP_PROTOCOL=grpc env configuration or specify http client explicitly:

exporter, _ := otlplogs.NewExporter(ctx, otlplogs.WithClient(otlplogsgrpc.NewClient()))

OTEL client with http/protobuf

Use OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf env configuration or specify http client explicitly:

exporter, _ := otlplogs.NewExporter(ctx, otlplogs.WithClient(otlplogshttp.NewClient(otlplogshttp.WithProtobufProtocol())))

OTEL client with http/json

Use OTEL_EXPORTER_OTLP_PROTOCOL=http/json env configuration or specify http client explicitly:

exporter, _ := otlplogs.NewExporter(ctx, otlplogs.WithClient(otlplogshttp.NewClient(otlplogshttp.WithJsonProtocol())))
