OpenTelemetry-Go OTLP Span Exporter
OpenTelemetry Protocol Exporter implementation.
Installation
go get -u go.opentelemetry.io/otel/exporters/otlp/otlptrace
Examples
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.
