gopsutil 是用go 实现python 写的psutil 的功能，并尝试在多平台上完整psutil 的函数。

下面是对内存的显示：

package main

import (
	"fmt"
	"github.com/shirou/gopsutil/mem"
)

func main(){
	v, _ := mem.VirtualMemory()

	// almost every return value is a struct
	fmt.Printf("Total: %v, Free:%v, UsedPercent:%f%%\n", v.Total, v.Free, v.UsedPercent)

	// convert to JSON. String() is also implemented
	fmt.Println(v)
}

在我的电脑上输出：

p, _ := process.NewProcess(pid) // Specify process id of parent

ps, _ := p.Children()
for _, v := range ps{
	err = v.Kill()  // Kill each child
	// handle error
}

p.Kill() // Kill the parent process
