npm install nodejs-system-infomonitor vital signs of your server :
- CPU usage %
- RAM usage %


[![NPM Version][npm-image]][npm-url]
[![NPM Downloads][downloads-image]][downloads-url]
One line installation with npm.
``bash`
$ npm i nodejs-system-info --save
Then in your code
`js
var systemInformation = require('nodejs-system-info');
const INTERVAL = 500;
const systemMonitor = new systemInformation(INTERVAL);
systemMonitor.log(['cpu', 'ram']);
`
require('nodejs-system-info').options
Default settings:
- cpu display CPU usage percentage. ram
- display RAM usage percentage. INTERVAL
- is 500 millisecond. Represents the refresh of the cpu and ram usage.
:warning: If this module uses too much CPU, set the INTERVAL value to 10000 or more.
If you have not supported in some categories, your OS configuration is not supported for this option.
`js
var systemInformation = require('nodejs-system-info');
const INTERVAL = 500;
const systemMonitor = new systemInformation();
setInterval(() => {
console.log(systemMonitor.get(['cpu']));
}, INTERVAL);
`$3
CPU average
`js
var systemInformation = require('nodejs-system-info');
const INTERVAL = 500;
const systemMonitor = new systemInformation(INTERVAL);
systemMonitor.log(['cpu']);
```
Interval: 500
CPU_Usage: 20.65%
RAM average
`js
var systemInformation = require('nodejs-system-info');
const INTERVAL = 500;
const systemMonitor = new systemInformation(INTERVAL);
systemMonitor.log(['ram']);
```
Interval: 500
RAM_Usage: 77.91%
js
const SystemInformation = require('nodejs-system-info');
const commandLineArgs = require('command-line-args');const DEFAULT_MONITOR_OPTIONS = ['cpu', 'ram'];
const optionDefinitions = [
{ name: 'interval', alias: 't', type: Number },
{ name: 'params', type: String, multiple: true, defaultOption: true }
];
const options = commandLineArgs(optionDefinitions);
const systemMonitor = new SystemInformation(options.interval);
systemMonitor.log(options.params || DEFAULT_MONITOR_OPTIONS);
`
Terminal Commands
`bash
node monitor.js (Default interval = 500ms, params = ram, cpu)(Custom set interval ---interval )
node monitor.js --interval 1000
(Custom interval and params default ram and cpu )
node monitor.js --interval 500 --params ram cpu
