OpenTelemetry-Go OTLP Span Exporter
OpenTelemetry Protocol Exporter implementation.
Installation
go get -u go.opentelemetry.io/otel/exporters/otlp/otlptrace
Examples
- HTTP Exporter setup and examples
- Full example of gRPC Exporter sending telemetry to a local collector
otlptrace
The otlptrace package provides an exporter implementing the OTel span exporter interface.
This exporter is configured using a client satisfying the otlptrace.Client interface.
This client handles the transformation of data into wire format and the transmission of that data to the collector.
otlptracegrpc
The otlptracegrpc package implements a client for the span exporter that sends trace telemetry data to the collector using gRPC with protobuf-encoded payloads.
otlptracehttp
The otlptracehttp package implements a client for the span exporter that sends trace telemetry data to the collector using HTTP with protobuf-encoded payloads.
Configuration
Environment Variables
The following environment variables can be used (instead of options objects) to override the default configuration. For more information about how each of these environment variables is interpreted, see the OpenTelemetry specification.
| Environment variable | Option | Default value |
|---|---|---|
OTEL_EXPORTER_OTLP_ENDPOINT OTEL_EXPORTER_OTLP_TRACES_ENDPOINT |
WithEndpoint WithInsecure |
https://localhost:4317 or https://localhost:43181 |
OTEL_EXPORTER_OTLP_CERTIFICATE OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE |
WithTLSClientConfig |
|
OTEL_EXPORTER_OTLP_HEADERS OTEL_EXPORTER_OTLP_TRACES_HEADERS |
WithHeaders |
|
OTEL_EXPORTER_OTLP_COMPRESSION OTEL_EXPORTER_OTLP_TRACES_COMPRESSION |
WithCompression |
|
OTEL_EXPORTER_OTLP_TIMEOUT OTEL_EXPORTER_OTLP_TRACES_TIMEOUT |
WithTimeout |
10s |
Configuration using options have precedence over the environment variables.

The gRPC client defaults to
https://localhost:4317and the HTTP clienthttps://localhost:4318. ↩︎
