upmon

Super simple service health monitoring.

Upmon sends a HTTP GET request to your configured URLs. It expects a HTTP 200 response. If it gets any other response code it'll send an email. If the service recovers, it'll send another email.

Getting started

1. npm install -g upmon upmon-mail

2. Create a new $HOME/.upmonrc file and add config:

   {
     "ping": {
       // Time in ms between pings
       "interval": 5000,
       // URL's of services to ping
       "services": ["http://localhost:8000/"]
     },
     "mail": {
       // Email from address
       "from": "[email protected]",
       // Email to address(es)
       "to": ["[email protected]"],
       // Nodemailer transport options
       // http://www.nodemailer.com/
       "transport": { 
         "service": "",
         "auth": {
           "user": "",
           "pass": ""
         } 
       }
     }
   }

Build your own monitor

Want to run upmon from guvnor or pm2?

Create a new project, add a .upmonrc config file, install the upmon modules you need, and pipe them together!

monitor.js

var upmon = require('upmon')
var mail = require('upmon-mail')
var sms = require('upmon-sms')

upmon().pipe(mail()).pipe(sms()).pipe(process.stdout)

pm2 start monitor.js
