如何配置golang性能监控框架以满足特定需求？

// main.go
package main

import (
    "bytes"
    "fmt"
    "net/http"

    "github.com/fortio/fortio/fhttp"
)

func main() {
    // TODO: Set specific performance metrics and targets
    metrics := []fhttp.MetricType{fhttp.HTTPOK}
    targets := fhttp.Config{
        QPS: fhttp.QPS{
            Mean:  50.0,
            Burst: 100.0,
        },
        Duration: "5s",
    }

    // Configure the HTTP request for your specific endpoint
    req := &http.Request{
        Method: "GET",
        URL:    &url.URL{Path: "/api/v1/users"}, // Replace with your actual endpoint
        Body:   bytes.NewBufferString("{}"),
    }

    // Create a Fortio client with the configured metrics and targets
    client := fortio.NewRunner()
    client.Config.Metrics = metrics
    client.Config.Targets = targets

    // Start the performance test
    results, err := client.Run(req)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(results)
}

// main.go
package main

import (
    "fmt"
    "log"
    "net/http"
    "net/http/pprof"
)

func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        // TODO: Add your application code here
    })

    // Register pprof handlers to serve performance profiles
    http.HandleFunc("/debug/pprof/", pprof.Index)
    http.HandleFunc("/debug/pprof/heap", pprof.Handler("heap"))
    http.HandleFunc("/debug/pprof/goroutine", pprof.Handler("goroutine"))

    log.Fatal(http.ListenAndServe("localhost:8080", nil))
}
