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);
});
