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：
