1、首先我们的服务需要打开pprof配置

		router := gin.Default()
		pprof.Register(router)
		mux.Handle("/", router)

2、生成profile文件

通过curl -o profile2  http://127.0.0.1:21111/debug/pprof/profile?debug=1

生成profile文件

3.通过go tool 工具生成分析图表

3.1 首先安装go的sdk

3.2 安装graphviz

    https://graphviz.gitlab.io/_pages/Download/windows/graphviz-2.38.msi 

    设置到path环境变量中 D:\go\Graphviz2.38\bin

3.3 测试graphviz是否安装成功

C:\Users\Administrator>dot -version
dot - graphviz version 2.38.0 (20140413.2041)
libdir = "D:\go\Graphviz2.38\bin"

    loadimage   :  (lib) bmp eps gd gd2 gif jpe jpeg jpg png ps svg

通过命令生成图表：

go tool pprof -http=:36666 d:\work\pprof\profile2

4.在生成图表的浏览器选择火焰图即可
