Functions

func NewMetricTripperware

func NewMetricTripperware(metrics *ClientMetrics, target string, next http.RoundTripper) promhttp.RoundTripperFunc

func NewMetricsMiddlewareHandler

func NewMetricsMiddlewareHandler(reg prometheus.Registerer, handlerName string, handler http.Handler) http.HandlerFunc

NewHandler wraps the given HTTP handler for instrumentation. It registers four metric collectors (if not already done) and reports HTTP metrics to the (newly or already) registered collectors: http_requests_total (CounterVec), http_request_duration_seconds (Histogram), http_request_size_bytes (Summary), http_response_size_bytes (Summary). Each has a constant label named "handler" with the provided handlerName as value. http_requests_total is a metric vector partitioned by HTTP method (label name "method") and HTTP status code (label name "code").
