API

Connection

connection: 'mongodb://localhost:27017/heartbeatdb',

Interval

The period of time between heartbeats,

interval: 5000

Monitor

Monitoring options. There are few strategies of heartbeating implemented now.

HTTP

HTTP/HTTPS requests, measure the request execution time and compare to !== 200 response code.

http: [
	{
		url: 'https://likeastore.com'
	},
	{
		url: 'https://stage.likeastore.com'
	}
]

JSON

HTTP/HTTPS requests for JSON API's.

json: [

		url: 'https://app.likeastore.com/api/monitor',
		response: {
			"app":"app.likeastore.com",
			"env":"production",
			"version":"0.0.52",
			"apiUrl":"/api"
		}
	}
],

MongoDB

For MongoDB checking, to run any query:

mongo: [
	{
		connection: 'mongodb://localhost:27017/likeastoredb',
		collections: ['users'],
		query: function (db, callback) {
			db.users.findOne({email: 'alexander.beletsky@gmail.com'}, callback);
		}
	}
]

Resolve

Resolves given dns name into ip addresses and pings each address.

resolve: [
	{
		name: 'google.com'
	}
]

Ping

Pings given ip address.

ping: [
	{
		ip: '37.139.9.95'
	}
]

Planned

Transport

To be able to send and receive emails and sms, mandrill and twilio accounts have to be setup.

mandrill: {
	token: "mandrill_access_token"
},

Twilio token
