Is It Up?

A Ruby gem that adds a simple endpoint to see if your application "is up". The endpoint is handled via Rack middleware. A Railtie is provided for integration with Ruby on Rails apps.

• Ruby 2.2 or higher
• Ruby on Rails 3.2 or higher

Add this line to your application's Gemfile:

gem 'is_it_up'

And then execute:

$ bundle

Or install it yourself as:

$ gem install is_it_up

IsItUp provides a monitoring URI that returns a JSON response:

% curl your-domain/is_it_up
{ "status": "ok", "code": 200 }

1. Fork it ( http://github.com/customink/is_it_up/fork )
2. Run bin/bootstrap_macos (if using macOS) and bin/setup to ensure your environment is configured for development
3. Run bin/test to ensure all tests pass
4. Create your feature branch (git checkout -b my-new-feature)
5. Commit your changes (git commit -am 'Add some feature')
6. Push to the branch (git push origin my-new-feature)
7. Create new Pull Request

Various ideas borrowed from:

• is_it_up, a similar rack middleware.
• fitter_happer, a similar Rails plugin.
