Examples

API

This example will create an API (ping) that configures the trace, creates a span and propagates to another API (pong). The ping API is configured to use itself as pong API.

The whole example runs in docker with a jaeger collecting the traces.

To run the example, run make run from this directory to create the API.

Wait for the API to start serving requests. It will print the message Application main loop starting now! on the logs.

After that, send a request using make send. You can change the parameters of the request on the docker-compose.yaml file.

Them visit http://localhost:16686/ to see the traces.

Example V1 compatibility

In the file trace/v2/examples/cmd/api/resources.go we apply the new middlewares. But if you want to test with the old trackingmiddleware.New, comment the trace and request middlewares and uncomment the trackingmiddleware.

	r.Use(
		// This is deprecated. Used when we can't ditch trace v1.
		// trackingmiddleware.New,
		// This is the preferred way
		trace.MuxHTTPMiddleware(""),
		request.HTTPMiddleware,
		enrichloggingmiddleware.New,
	)
