Heartbeat

Health monitoring of HTTP services and databases.

Requirements

• MongoDB
• NodeJS > 0.10.x
• Mandrill

You decide what to use for notifications, Mandrill (emails), Twilio (sms) or both.

How to use

Clone the repo and install dependenices,

$ git clone git://github.com/likeastore/heartbeat
$ cd heartbeat
$ npm install

Create index.js in /config folder,

module.exports = {
	connection: 'mongodb://localhost:27017/heartbeatdb',

	interval: 10000,

	logentries: {
		token: null
	},

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

					"version":"0.0.52",
					"apiUrl":"/api"
				}
			}
		],

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

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

		ping: [
			{
				ip: '37.139.9.95'
			}
		]

			from: '[email protected]',
			to: ['[email protected]']
		},

		sms: {
			to: ['+3805551211', '+3805551212']
		}
	},

	transport: {
		mandrill: {
			token: 'fake-token'
		},

		twilio: {
			sid: 'fake-sid',
			token: 'fake-token'
		}
	}
};

Start heart beating,

$ node app.js

API

Connection

Connection string to MongoDB to store heartbeat results.

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: '[email protected]'}, 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

• MySQL
• Redis
• REST hooks

Transport

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

Mandril token

Mandrill access token,

mandrill: {
	token: "mandrill_access_token"
},

Twilio token

Twilio access token,

twilio: {
	sid: "twilio_sid",
	token: "twilio_access_token"
}
