loadavg-windows

About

Use require('loadavg-windows') to enjoy os.loadavg() on Windows OS (or force using custom implementation on any other OS).

Motivation

Currently Node.js on Windows platform do not implements os.loadavg() functionality - it returns [0,0,0]

Important details

• os.loadavg() returns [A, B, C]
  • A - expect value different than 0 after few seconds.
  • B - expect value different than 0 after first 5 minutes.
  • C - expect value different than 0 after first 15 minutes.
• Requiring it on other operating systems have NO influence, unless require('loadavg-windows').enableCustomLoadavg() called manually.

Usage

Just one line required to enjoy os.loadavg() on Windows OS:

require('loadavg-windows');
 
setInterval( () => {
  console.log( os.loadavg() );
}, 3000);

Can be activated on any other OS in case native version not working (on Windows OS it is enabled by default)

const { useCustomLoadavg } = require('loadavg-windows');
useCustomLoadavg();

Installation

Requires Node.js v4.8.7

npm install loadavg-windows

Not important details:

This is pure JavaScript, platform-independent implementation of os.loadavg() that can be used on Windows system (or any other system that for some reasons do not supports loadavg)

It uses only os.cpus() for proper calculations.
