OpenTelemetry-Go OTLP Span Exporter

OpenTelemetry Protocol Exporter implementation.

Installation

go get -u go.opentelemetry.io/otel/exporters/otlp/otlptrace

Examples

• Exporter setup and examples
• Full example 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.
