618臨近了，介紹一個go版本的系統採集工具包 gopsutil ；python也有同樣的工具包psutil，及時上手一個小腳本跑一把體驗下；功能還是很豐富的。go語言本身擁有極強的性能，也非常適合做一些後端的數據採集管理以及運維繫統。廢話不多說，直接來個示例走一下。

示例：
package main
import (
"fmt"
"time"
"github.com/shirou/gopsutil/cpu"
"github.com/shirou/gopsutil/disk"
"github.com/shirou/gopsutil/host"
"github.com/shirou/gopsutil/mem"
"github.com/shirou/gopsutil/net"
)
func main() {
v, _ := mem.VirtualMemory()
c, _ := cpu.Info()
cc, _ := cpu.Percent(time.Second, false)
d, _ := disk.Usage("/")
n, _ := host.Info()
nv, _ := net.IOCounters(true)
boottime, _ := host.BootTime()
btime := time.Unix(int64(boottime), 0).Format("2006-01-02 15:04:05")
fmt.Printf("Mem : %v MB Free: %v MB Used:%v Usage:%f%%\n", v.Total/1024/1024, v.Available/1024/1024, v.Used/1024/1024, v.UsedPercent)
if len(c) > 1 {
for _, sub_cpu := range c {
modelname := sub_cpu.ModelName
cores := sub_cpu.Cores
fmt.Printf("CPU : %v %v cores \n", modelname, cores)
}
} else {
sub_cpu := c[0]
modelname := sub_cpu.ModelName
cores := sub_cpu.Cores
fmt.Printf("CPU : %v %v cores \n", modelname, cores)
}
fmt.Printf("Network: %v bytes / %v bytes\n", nv[0].BytesRecv, nv[0].BytesSent)
fmt.Printf("SystemBoot:%v\n", btime)
fmt.Printf("CPU Used : used %f%% \n", cc[0])
fmt.Printf("SSD : %v GB Free: %v GB Usage:%f%%\n", d.Total/1024/1024/1024, d.Free/1024/1024/1024,d.UsedPercent)
fmt.Printf("OS : %v(%v) %v \n", n.Platform, n.PlatformFamily, n.PlatformVersion)
fmt.Printf("Hostname : %v \n", n.Hostname)
}
結果：
