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:4318[^1]
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

[^1]: The gRPC client defaults to https://localhost:4317 and the HTTP client https://localhost:4318.

Configuration using options have precedence over the environment variables.
