Functions

func InitJaeger

func InitJaeger(ctx context.Context, service string) (opentracing.Tracer, io.Closer, error)

initJaeger returns an instance of Jaeger Tracer that samples 100% of traces and logs all spans to stdout.

func InitLightstep

func InitLightstep(service string, accessToken string) lightstep.Tracer

func Register

func Register(tracer *mocktracer.MockTracer, ss traces.SpanStore, r *mux.Router) error
