OpenTelemetry-Go Jaeger Exporter

OpenTelemetry span exporter for Jaeger implementation.

Installation

go get -u go.opentelemetry.io/otel/exporters/jaeger

Example

See ../../example/jaeger.

Configuration

The exporter can be used to send spans to:

• Jaeger agent using jaeger.thrift over compact thrift protocol via WithAgentEndpoint option.
• Jaeger collector using jaeger.thrift over HTTP via WithCollectorEndpoint option.

Environment Variables

The following environment variables can be used (instead of options objects) to override the default configuration.

Environment variable	Option	Default value
OTEL_EXPORTER_JAEGER_AGENT_HOST	WithAgentHost	localhost
OTEL_EXPORTER_JAEGER_AGENT_PORT	WithAgentPort	6831
OTEL_EXPORTER_JAEGER_ENDPOINT	WithEndpoint	http://localhost:14268/api/traces
OTEL_EXPORTER_JAEGER_USER	WithUsername
OTEL_EXPORTER_JAEGER_PASSWORD	WithPassword

Configuration using options have precedence over the environment variables.

Contributing

This exporter uses a vendored copy of the Apache Thrift library (v0.14.1) at a custom import path. When re-generating Thrift code in the future, please adapt import paths as necessary.
