木有，hc也需要手动 |
同求! |

go-zero 如何接入 pprof 工具，我这简单总结了下：
|
How go-zero accesses the pprof tool, I briefly summarize it: |
|
有内置的，看 |
There are built-in ones, see |
好的，我看看，谢谢 |
ok, i'll take a look, thanks |

这个就不需要了，删掉 |

//我根据博主文档整理一份完整demo，goctl1.3.5生成的API
package main

你好，使用kill -usr2 后 打不开trace.pprof文件，其他文件可以打开 go tool pprof core-1-trace-1201111253.pprof |

我是这样实现的，创建 package handler
import (
"github.com/zeromicro/go-zero/rest"
"net/http"
"net/http/pprof"
"ticket_saas/api/internal/svc"
)
func RegisterMonitorHandler(server *rest.Server, serverCtx *svc.ServiceContext) {
server.AddRoutes(
rest.WithMiddlewares(
[]rest.Middleware{},
[]rest.Route{
{
Method: http.MethodGet,
Path: "/debug/pprof",
Handler: pprof.Index,
},
{
Method: http.MethodGet,
Path: "/debug/allocs",
Handler: pprof.Handler("allocs").ServeHTTP,
},
{
Method: http.MethodGet,
Path: "/debug/block",
Handler: pprof.Handler("block").ServeHTTP,
},
{
Method: http.MethodGet,
Path: "/debug/cmdline",
Handler: pprof.Handler("cmdline").ServeHTTP,
},
{
Method: http.MethodGet,
Path: "/debug/goroutine",
Handler: pprof.Handler("goroutine").ServeHTTP,
},
{
Method: http.MethodGet,
Path: "/debug/heap",
Handler: pprof.Handler("heap").ServeHTTP,
},
{
Method: http.MethodGet,
Path: "/debug/mutex",
Handler: pprof.Handler("mutex").ServeHTTP,
},
{
Method: http.MethodGet,
Path: "/debug/profile",
Handler: pprof.Handler("profile").ServeHTTP,
},
{
Method: http.MethodGet,
Path: "/debug/threadcreate",
Handler: pprof.Handler("threadcreate").ServeHTTP,
},
{
Method: http.MethodGet,
Path: "/debug/trace",
Handler: pprof.Handler("trace").ServeHTTP,
},
{
Method: http.MethodGet,
Path: "/debug/symbol",
Handler: pprof.Symbol,
},
{
Method: http.MethodGet,
Path: "/debug/vars",
Handler: http.DefaultServeMux.ServeHTTP,
},
}...,
),
)

框架没有接入pprof 进行性能剖析,需要自己进行接入
