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

Notice, however, that by default the generator uses the UDP exporter of jaeger-client-go, which sends data to localhost, i.e. inside the networking namespace of the container itself, which obviously doesn't go anywhere. You can use the environment variables supported by jaeger-client-go to instruct the SDK where to send the data, for example to switch to HTTP by setting JAEGER_ENDPOINT.

See example in the included docker-compose file.
