golang pprof

[eastany]

import _ "net/http/pprof"

func main(){
    go func() {
                log.Println(http.ListenAndServe("localhost:6060", nil))
        }()
}

访问 http://127.0.0.1:6060/debug/pprof/ 会有基本的一些数据 再执行 go tool pprof http://localhost:6060/debug/pprof/profile 会进入30s的采样 随后(pprof):web 即可生成调用消耗的svg图 top10

PS：生成svg图需要安装graphviz
