简介

什么是 gopsutil?要说gopsutil就不得不先了解 psutil,顾名思义,psutil = process and system utilities, 它是 Python 的跨平台库,能够轻松实现获取系统运行的进程和系统利用率,包括 CPU、内存、磁盘、网络等信息。而gopsutil就是psutil的 Golang 移植版。

为什么用 gopsutil?和直接使用 syscall 调用对应的系统方法相比,gopsutil 为我们屏蔽了各个系统间的差异,可移植性非常强。

快速上手

安装:

go get github.com/shirou/gopsutil

使用:

package main

import (
    "fmt"
    "github.com/shirou/gopsutil/cpu"
    "time"
)

func main() {
    info, _ := cpu.Info()

    per, _ := cpu.Percent(1 * time.Second, true)

    fmt.Printf("CPU Percent: %fn", per)

    fmt.Println(info)
}

输出:

CPU Percent: [4.040404 4.000000 5.050505 6.930693]

分工明确

gopsutil 将不同的功能划分到不同的子包中:主要为 cpu,disk,docker,host,mem,net,process,winservices 这几个。想要使用对应的功能,要导入对应的子包。例如,上面代码中,我们要获取 CPU 信息,导入的是 cpu 子包。上述样例中,我们获取到了每个 cpu 的占用率和所有 cpu 的详细信息。

闲言

最近正在写一个 Golang 实现性能监控的 demo,之后还会写这方面的介绍或者对比。
