Simple webdis-like application for heroku written in nodejs, lets you run HGETALL/HGET/HSET/SET/GET/HMGET commands on a redis instance from client side javascript, or command line via wget; get your data back in JSON format. Basically lets you turn an heroku instance into a cheap JSON key value store. Also implements logic for remote host checking in, in order to send a tweet when an host hasnt checked in the maximum alloted time. This is used in conjunction with cron jobs on the remote host to implement a very basic network status checker and network problem alerter.
Additionally serves a rudimentary management page for redis (at http://root/redis) from where you can inspect keys and hashes and their values (hashes and keys only for now)
Also implements a CHECKIN command, with one parameter, that automatically updates an hash (whose name is stored in the checkinsHashName var) using its parameter as a key and the current datetime as a value. This is then used on a page, served at http://root/CHECK/it , that displays elapsed time since the last checkin for any given key/host.
Warning
This is not meant to be run on a public server in apublic application as it lacks any kind of access control. If you need security, try webdis ( https://github.com/nicolasff/webdis , http://webd.is ) This is only intended for running inside your intranet.
How to run
Deploy to heroku. Assuming you have a redistogo instance running, the JSON key value store will be aumatically available. If you use it to set a value for an hostname in the controlledHosts hash, like this:
http://approot/HSET/controlledHosts/myhost/300
You will be notified via twitter every 60 seconds if no one has called the url
http://approot/CHECKIN/myhost in the last 5 minutes (300 seconds)
..if you have provided your oAuth credentials.
