vendor: vendor with -compat=1.17
This might break compatibility with projects using this module that
are still on go1.16, which is EOL, so probably ok to ignore:

    github.com/docker/buildx/store imports
        github.com/gofrs/flock tested by
        github.com/gofrs/flock.test imports
        gopkg.in/check.v1 loaded from gopkg.in/check.v1@v1.0.0-20200227125254-8fa46927fb4f,
        but go 1.16 would select v1.0.0-20201130134442-10cb98267c6c

    To upgrade to the versions selected by go 1.16:
        go mod tidy -go=1.16 && go mod tidy -go=1.17
    If reproducibility with go 1.16 is not needed:
        go mod tidy -compat=1.17
    For other options, see:
        https://golang.org/doc/modules/pruning

OpenTelemetry-Go OTLP Span Exporter

Go Reference

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.

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
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.
