Usage

package main

import (
	"net/http"

	"github.com/labstack/echo/v4"
	"github.com/labstack/echo-contrib/pprof"

)

func main() {
	e := echo.New()
	pprof.Register(e)
    ......
	e.Logger.Fatal(e.Start(":1323"))
}

• Then use the pprof tool to look at the heap profile:

  go tool pprof http://localhost:1323/debug/pprof/heap

• Or to look at a 30-second CPU profile:

  go tool pprof http://localhost:1323/debug/pprof/profile?seconds=30

• Or to look at the goroutine blocking profile, after calling runtime.SetBlockProfileRate in your program:

  go tool pprof http://localhost:1323/debug/pprof/block

• Or to look at the holders of contended mutexes, after calling runtime.SetMutexProfileFraction in your program:

  go tool pprof http://localhost:1323/debug/pprof/mutex
