tracegen

tracegen

tracegen is a utility that can generate a steady flow of simple traces useful for performance tuning. Traces are produced concurrently from one or more worker goroutines. Run with -h to see all cli flags.

The binary is available from the Releases page, as well as a Docker image:

$ docker run jaegertracing/jaeger-tracegen -service abcd -traces 10

The generator can be configured to export traces in different formats, via -exporter flag. By default, the exporters send data to localhost. If running in a container, this refers to the networking namespace of the container itself, so to export to another container (like Jaeger Collector), the exporters need to be provided with appropriate location. Exporters accept configuration via environment variables:

• Jaeger exporter: see https://github.com/open-telemetry/opentelemetry-go/blob/main/exporters/jaeger/README.md
• OTLP exporter: see https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/protocol/exporter.md

See example in the included docker-compose file.
