OS Toolbox

Installation

$ npm install os-toolbox

Usage

var ostb = require( 'os-toolbox' );

Before use

/!\ All functions use promises !

Get platform

Get platform name.

ostb.platform(); //ex : linux

Get uptime

Get system uptime in seconds.

ostb.uptime(); //ex : 419419

Get CPU load

Get cpu load percentage.

ostb.cpuLoad().then(function(cpuusage){
   console.log(cpuusage); //ex: 34 (percent)
});

Get memory usage

Get memory usage percentage.

ostb.memoryUsage().then(function(memusage){
   console.log(memusage); //ex: 93 (percent)
}, function(error){
    //errors here
});

Get current processes

Get current running processes.

ostb.currentProcesses().then(function(processes){
   console.log(processes);
}, function(error){
    //errors here
});

Using sort :

Results could be sort by each attributes (cpu, memory, pid ...) (cf example)

Sort param format:

• type: pid, name, cpu or mem
• order: asc or desc

   { 
       type: 'cpu', 
       order: 'desc'
    }

Exemple:

ostb.currentProcesses(sort).then(function(processes){
   console.log(processes);
}, function(error){
    //errors here
});

The following is an example current processes output :

[ { pid: 2316, name: 'code', cpu: 4, mem: 1.114957060891639 },
  { pid: 2310, name: 'nautilus', cpu: 8, mem: 0.989467485779745 },
  { pid: 3867, name: 'notify-osd', cpu: 0, mem: 0.8229067957850149 },
  { pid: 2312, name: 'albert', cpu: 1, mem: 0.8190965839223904 },
  { pid: 1716, name: 'code', cpu: 0.3, mem: 0.8020248554469948 },
  { pid: 2457, name: 'code', cpu: 1.6, mem: 0.7947013313474048 }
]

Get system services list (Linux only)

Get system services list.

ostb.services().then(function (result) {
   console.log(result);
}, function(error){
    //errors here
});

Using filters :

Results could be filtered by service name (cf example)

Filters param format:

   [{name: 'service'}, {name: ....]

Exemple:

ostb.services(filters).then(function (result) {
   console.log(result);
}, function(error){
    //errors here
});

The following is an example system services output :

[ { name: 'apache2', runing: false },
  { name: 'cron', runing: true },
  { name: 'dbus', runing: false },
  { name: 'exim4', runing: false },
  { name: 'nginx', runing: false },
  { name: 'php5-fpm', runing: false },
  { name: 'postgresql', runing: false },
  { name: 'procps', runing: false },
  { name: 'rabbitmq-server', runing: false },
  { name: 'redis-server', runing: false },
  { name: 'resolvconf', runing: true },
  { name: 'rsync', runing: false },
  { name: 'rsyslog', runing: false },
  { name: 'sudo', runing: false },
  { name: 'udev', runing: false },
  { name: 'unattended-upgrades', runing: false },
  { name: 'urandom', runing: false },
  { name: 'x11-common', runing: false } ]
