Website uptime Event Emitter

Ping-monitor (Node-Monitor) is a tool for monitoring your website's uptime. If the website is up or down an event is emitted. This module is extracted from Node Ping, an uptime app I wrote recently.

Installation

npm install ping-monitor

How to use

var Monitor = require('ping-monitor');

 

var myWebsite = new Monitor(options);

 

myWebsite.on(event, callback(response) {

    // Do something with the response 

});

Options

• website (* required) - The url of the website to be monitored.
• interval (defaults to 15) - time interval(in minutes) for checking website availability.

Emitted Events

• up - All is good website is up.
• down - Not good, website is down.
• error - Bad, http request module cannot load website.
• stop - Fired when the monitor has stopped.

response object

• object.website - website being monitored.
• object.time - time in milliseconds.
• object.responseCode - http response code.
• object.responseMessage - http response code message.

Example

var Monitor = require('ping-monitor');

var request = require('request'); 

const token = 'Line Token';

var headers = {

    'User-Agent':       'Super Agent/0.0.1',

    'Content-Type':     'application/x-www-form-urlencoded'

}

// Configure the request

var options = {

    'url': 'https://notify-api.line.me/api/notify',

    'method': 'POST',

    'headers': headers,

'auth': {

       'bearer': token

},

'form': {

       'message': ''

}

}

var myWebsite = new Monitor({

    website: 'http://www.tapee.ac.th',

    interval: 1

});

myWebsite.on('error', function (msg) {

    console.log(msg);

    options.form.message = 'http://www.tapee.ac.th  is error! ';

    request(options);

});

myWebsite.on('up', function (res) {

    console.log('Yay!! ' + res.website + ' is up.');

});

myWebsite.on('down', function (res) {

    options.form.message = 'http://www.tapee.ac.th  is down! ';

    request(options);

    console.log( res.website + ' is down! ' + res.statusMessage);

});
