RouteCounter

When you want to know how much your routes are being used.

This is particularly useful if you are wondering if they are used at all.

Add this line to your application's Gemfile:

gem 'route_counter'

And then execute:

$ bundle

Or install it yourself as:

$ gem install route_counter

Enable the recording in an initializer and insert the middleware:

  RouteCounter.config.enabled = true
  Rails.application.config.middleware.use RouteCounter::Middleware

Add to Rakefile:

require "route_counter/tasks"

Check what's been used.

  $ bundle exec rake routes:count:local

All of this gets stored on your disk. If you want to clear it out.

  $ bundle exec rake route_counter:local:clear

You might want to see the counts across your servers. This will use Redis to aggregate info from across all of them. First, you'll need to tell it where Redis is:

RouteCounter.config.redis = Redis.new(connection_hash)

Then, you can clear out the remote store. Or not to be cumulative to last time you took a snapshot

  $ bundle exec rake route_counter:global:clear

Then take a snapshot. You can do this in parallel on all of your servers (with Capistrano for example).

  $ bundle exec rake route_counter:snapshot

Then on one of the servers you can run to use the global numbers

  $ bundle exec rake routes:count:global

• could make a middleware (or config option) that wrote directly to Redis
• should it record more info about the request?
• configurable error handler
