01-gopsutil包使用

系统监控库-gopsutils

简介

在说gopsutils之前我们必须先说下psutils是啥, 因为gopsutils实际上就是一个golang版本的psutils(从名字上也能看出来)
psutils是一个比较出名的python库, psutils是python process and system utilities的一个缩写. 它有如下特点

• 跨平台: Linux, Windows, OSX, Sun Solaris, FreeBSD, OpenBSD and NetBSD的32位和64位系统
• 功能丰富: 实现了进程管理,系统诊断, 这个库基本实现了这些命令行工具的功能: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap

如果想要了解关于gopsutils更多的详情 请查看gopsutils github地址

安装

go get  -v "github.com/shirou/gopsutil"

使用

具体的使用文档可以参考gopsutil的godoc文档
以下以测试收集cpu, disk, load, mem, net, process 为列, 注意这些对象都使用String方法, 因此可以直接调用fmt打印，String方法会将其转换成Json输出.

package main
import (
	"fmt"
	"github.com/shirou/gopsutil/cpu"
	"github.com/shirou/gopsutil/disk"
	"github.com/shirou/gopsutil/load"
	"github.com/shirou/gopsutil/mem"
	"github.com/shirou/gopsutil/net"
	"github.com/shirou/gopsutil/process"
)
func main() {
	fmt.Println("CPU统计:")
	c, _ := cpu.Info()
	fmt.Println(c)
	fmt.Println("内存统计:")
	m, _ := mem.VirtualMemory()
	fmt.Println(m)
	fmt.Println("磁盘用量和IO统计:")
	dp, _ := disk.Partitions(true)
	du, _ := disk.Usage("/")
	di, _ := disk.IOCounters()
	fmt.Println(du)
	fmt.Println(dp)
	fmt.Println(di)
	fmt.Println("网络IO统计:")
	ni, _ := net.IOCounters(true)
	fmt.Println(ni)
	fmt.Println("协议统计:")
	nt, _ := net.ProtoCounters(nil)
	fmt.Println(nt)
	fmt.Println("链接状态统计:")
	nc, _ := net.Connections("all")
	fmt.Println(nc)
	fmt.Println("进程统计:")
	pi, _ := process.Pids()
	fmt.Println(pi)
	p, _ := process.NewProcess(614)
	pm, _ := p.MemoryPercent()
	pn, _ := p.Username()
	fmt.Println(pm)
	fmt.Println(pn)
	fmt.Println("负载统计:")
	pl, _ := load.Avg()
	fmt.Println(pl)
}

最后执行过会的结果大概为这样:
