os-utils

An operating system utility library. Some methods are wrappers of node libraries and others are calculations made by the module.

Installation

One line installation with npm.

npm install os-utils

Then in your code

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


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

os.cpuFree(function(v){
	console.log( 'CPU Free:' + v );
});

Usage

The following methods are available:

Calculate CPU usage for the next second

This is not an average of CPU usage like it is in the "os" module. The callback will receive a parameter with the value.

os.cpuUsage( function(value) { /* ... */ } );

Calculate free CPU for the next second

This is not based on average CPU usage like it is in the "os" module. The callback will receive a parameter with the value.

os.cpuFree( function(value) { /* ... */ } );

Get the platform name

os.platform();

Get number of CPUs

os.cpuCount()

Get current free memory

os.freemem()

Get total memory

os.totalmem()

Get a current free memory percentage

os.freememPercentage()

Get the number of seconds the system has been running for

os.sysUptime();

Get the number of seconds the process has been running

os.processUptime() 

Get average load for 1, 5 or 15 minutes

os.loadavg(1)
os.loadavg(5)
os.loadavg(15)
