Overview

Package gohttpmetrics knows how to measure http metrics in VictoriaMetrics format. it comes with a middleware that can be used for the main Go net/http handler:

package main

import (
	"log"
	"net/http"

	victoriametrics "github.com/VictoriaMetrics/metrics"
	victoria "github.com/dottedmag/go-http-metrics/metrics/victoria"
	httpmiddleware "github.com/dottedmag/go-http-metrics/middleware"
	httpstdmiddleware "github.com/dottedmag/go-http-metrics/middleware/std"
)

func main() {
	// Create our middleware.
	mdlw := victoria.New(victoria.Config{})

	// Our handler.
	myHandler := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		w.WriteHeader(http.StatusOK)
		w.Write([]byte("hello world!"))
	})
	h := httpstdmiddleware.Handler("", mdlw, myHandler)

	// Serve metrics.
	log.Printf("serving metrics at: %s", ":9090")
	go http.ListenAndServe(":9090", promhttp.Handler())

	// Serve our handler.
	log.Printf("listening at: %s", ":8080")
	if err := http.ListenAndServe(":8080", h); err != nil {
		log.Panicf("error while serving: %s", err)
	}
}
