Zipkin tracer DSL for Golang

How to use:

Declare the environment variable ZIPKIN_URL with the protocol://host:port of the Zipkin collector.

Example: http://127.0.0.1:9411

Otherwise, it will use http://127.0.0.1:9411 as default value.

How to trace:

Trace your endpoints

func Handlers() http.Handler {
	r := mux.NewRouter()
	tracing.StartTracing("localhost:8080", "users")

	r.HandleFunc("/healthcheck", handlers.HealthcheckHandler()).Name("/healthcheck")
	return r
}
err := http.ListenAndServe(":8080", tracing.TrackerHandler(Handlers()))

Trace your methods

trace := tracing.Trace("My API")
[YOUR CODE]
defer trace.Finish()

Trace your methods with parent

parent := tracing.Trace("Other API")
[YOUR CODE]
	span := tracing.TraceParent("Get Another API", parent)
	defer span.Finish()
defer parent.Finish()
