我从未见过比 0.0% 我的应用程序上的cpu。还搜索了 cf apps 除了 0.0% . 这是吗 0.0% 来自VM、容器或管理程序?该值是如何计算的?此值是否由健康经理收集?我可以相信这个值吗?

CloudFoundry在OpenStack集群上运行。

我认为信息流是:

cf CLI<->云控制器<->DEA<->管理员<->cgroup CPU记帐

参见:

这里的统计数据显示了容器中的进程在上一秒中在CPU(虚拟机)上花费的时间百分比。如果您的应用程序要做一些CPU密集型的事情,您可能会看到这个数字增加。例如,我推了一个小的hello world Golang应用程序,它也在后台运行一个紧密的循环,计算一些随机浮点数的正弦值,然后 cf app 显示15.5%的CPU使用率:

package main

import (
    "fmt"
    "net/http"
    "os"
    "math"
    "math/rand"
)

func main() {
    go func() {
        for {
            println(math.Sin(rand.Float64()))
        }
    }()

    http.HandleFunc("/", hello)
    fmt.Println("listening...")
    err := http.ListenAndServe(":"+os.Getenv("PORT"), nil)
    if err != nil {
        panic(err)
    }
}

func hello(res http.ResponseWriter, req *http.Request) {
    fmt.Fprintln(res, "go, world")
}
