How to obtain using Node Js the use of processing, memory, load average and operating system information?

I know that in Java, for example, the library "OperatingSystemMXBean" would like an equivalent.

The native module 'os' is a good option?

node.js

I'm doing this query, and I need to check the cost value of a product using a subquery, because the note table is the same as input and output. Products do not repeat. What sets sales apart and cost. It's the note series. It is returning the cost as null. But if I include a product code manually. It works.

With the module you can get the CPU and memory information:

const os = require('os');

console.log(os.cpus());
console.log(os.totalmem());
console.log(os.freemem())

The os-utils module is also interesting, it works in much the same way:

const os = require('os-utils');

os.cpuUsage(function(v){
    console.log( 'CPU Usage (%): ' + v );
});

Disk usage information you can use diskspace :

const diskspace = require('diskspace');

diskspace.check('C', function (err, result) {
    console.log(JSON.stringify(result))
});
