History

Sebastiaan van Stijn 35b238ee82 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 Signed-off-by: Sebastiaan van Stijn <github@gone.nl>		3 years ago

README.md

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.

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.
