go pprof

import _ "net/http/pprof"

func main() {
	go func() {
	     http.ListenAndServe("localhost:6060", nil)
        }()
        /** your logic code */
}

 

you can check the web status by this url :  http://localhost:6060/debug/pprof/

 

 

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

go tool pprof http://localhost:6060/debug/pprof/heap
Or to look at a 30-second CPU profile:

go tool pprof http://localhost:6060/debug/pprof/profile
Or to look at the goroutine blocking profile:

go tool pprof http://localhost:6060/debug/pprof/block
