如何在node.js中获取服务器CPU，内存和磁盘百分比

var os  = require('os-utils');
os.cpuUsage(function(v){
    console.log( 'os-utils CPU Usage (%): ' + v ); 
    // os-utils CPU Usage (%): 0.11180382377389864
});
os.cpuFree(function(v){
    console.log( 'os-utils CPU Free:' + v );
    // os-utils CPU Free:0.8876135425268373
});

var osu = require('node-os-utils')
var cpu = osu.cpu
cpu.usage()
.then(info => {
    console.log('node-os-utils cpu.usage '+info)
    // node-os-utils cpu.usage 11.53
})
cpu.free()
.then(info => {
    console.log('node-os-utils cpu.free '+ info)
    // node-os-utils cpu.free 88.47
})

太烦人了。为什么OS-Utils值与Node-OS-Utils值不同？我需要当前运行node.js的服务器的CPU和磁盘内存值 - 电流CPU使用**（百分比） - 可用内存*（免费/总计） - 可用磁盘空间（免费/总计）

var os  = require('os-utils');
os.cpuUsage(function(v){
    console.log( 'os-utils CPU Usage (%): ' + v ); 
    // os-utils CPU Usage (%): 0.11180382377389864
});
os.cpuFree(function(v){
    console.log( 'os-utils CPU Free:' + v );
    // os-utils CPU Free:0.8876135425268373
});

var osu = require('node-os-utils')
var cpu = osu.cpu
cpu.usage()
.then(info => {
    console.log('node-os-utils cpu.usage '+info)
    // node-os-utils cpu.usage 11.53
})
cpu.free()
.then(info => {
    console.log('node-os-utils cpu.free '+ info)
    // node-os-utils cpu.free 88.47
})

it's so annoying.
Why is the os-utils value different from the node-os-utils value?
I need the CPU and disk memory values of the server currently running node.js
-Current CPU usage** (percent)
-Available memory* (free/total)
-Available disk space (free/total)

似乎OS-UTILS软件包运行良好。仅给出0到1的百分比格式，含义0 =＆gt; 0％和1 =＆gt; 100％等等。

关于获取磁盘空间卷信息，您可以使用软件包diskusage。
您可以在那里查看文档 https://www.npmjs.coms.com/package/package/diskusage/diskusage

const disk = require('diskusage');

// get disk usage. Takes mount point as first parameter
disk.check('/', function(err, info) {
    const freeInPercentage = info.free / info.total;
    const usedInPercentage = info.available / info.total;

    console.log(`free disk space: ${freeInPercentage * 100}%`);
    console.log(`used disk space: ${usedInPercentage * 100}%`);
});

It seems like os-utils package works well. Just format of percentage was given from 0 to 1, meaning 0 => 0% and 1 => 100% and so on.

About getting disk space volume info you can use package diskusage.
You can check docs there https://www.npmjs.com/package/diskusage

const disk = require('diskusage');

// get disk usage. Takes mount point as first parameter
disk.check('/', function(err, info) {
    const freeInPercentage = info.free / info.total;
    const usedInPercentage = info.available / info.total;

    console.log(`free disk space: ${freeInPercentage * 100}%`);
    console.log(`used disk space: ${usedInPercentage * 100}%`);
});
