About

Basic system usage monitor.

Gives you a simple CPU and RAM usage percentage with zero dependencies.

Usage

Install using npm:

$ npm install sysusage

This will also add a sysusage command that prints the 1s and 10s CPU usage along with the RAM usage.

getMemoryUsage

Returns system memory usage percent.

const { getMemoryUsage } = require('sysusage');

console.log(getMemoryUsage());

createCpuCalculator

This creates a function that returns the CPU usage using a window of X calls (defaults to 1).

const { createCpuCalculator } = require('sysusage');

const getCpuUsage = createCpuCalculator();
setTimeout(() => console.debug(getCpuUsage()), 1000);

For example to get the usage of the previous 10 seconds, use a size of 10 with a 1 second interval:

const { createCpuCalculator } = require('sysusage');

const getCpuUsage = createCpuCalculator(10);
setInterval(() => console.debug(getCpuUsage()), 1000);
