Functions

func AnnotateRequest

func AnnotateRequest(req *http.Request, route string) *http.Request

AnnotateRequest adds telemetry related annotations to request context and returns. The request context on the returned request should be retained. Ensure `route` is a route template and not actual URL to prevent high cardinality on the metrics.

LabelerFromContext returns the labeler annotation from the context if exists.
