A really easy way to monitor the health of a list of endpoints over time.

Add to your Gemfile:

source 'https://rubygems.org'
gem 'eir'

At your project root, create a uris.yaml YAML file of the URIs you wish to monitor, e.g.:

- http://www.google.co.uk : Google
- http://www.yahoo.co.uk : Yahoo
- http://www.itv.com : ITV

From the console, navigate to your project root and simply run:

$ eir

A lightweight Sinatra app will start at http://localhost:8700.

Both a pidfile and logs will be generated at server.pid, eir_access.log and eir_error.log.

A successfully running app should have a directory structure like this:

.
├── Gemfile
├── Gemfile.lock
├── eir_access.log
├── eir_error.log
├── server.pid
└── uris.yaml

1. Test connection error cases
2. Parse/validate URIs
3. Validate YAML
4. Some decent CSS/JS (please help!)
