I just released a new version of pulse. Pulse adds an action to your rails project that can be used for external health checking. The most common use is by a http proxy such as haproxy.

The main new feature of version 0.2.0 is that the pulse URL is now specified in routes.rb. For example, you might like /heartbeat better than /pulse. The URL is set up in config/routes.rb like:

map.pulse 'pulse_url'

For example, config/routes.rb might look like:

ActionController::Routing::Routes.draw do |map|
  map.connect ':controller/:action/:id'
  map.pulse 'pulse'

Pulse is now a rails plugin instead of a gem, so check out the new installation instructions.

Pulse no longer monkey patches rails in the manner described in Add routes with a rails plugin or gem. Now, it mixes a Pulse::Routes module into ActionController::Routing::RouteSet::Mapper. This allows the “map.pulse” syntax that is shown above.

The code (lib/routes.rb) looks like:

module Pulse
  module Routes
    def pulse(path)
      connect path, :controller => 'pulse', :action => 'pulse'

ActionController::Routing::RouteSet::Mapper.send :include, Pulse::Routes
