ControllerRuntime

Install the gem and add to the application's Gemfile by executing:

$ bundle add controller_runtime

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install controller_runtime

You first need to publish the events you want to track. For example, if you want to track the time it takes to make a request to GitHub via the Octokit gem, you can create a custom client that publishes an event via ActiveSupport::Notifications when a request is made:

# app/lib/octokit/instrumented_client.rb
module Octokit
  class InstrumentedClient
    def initialize(**attrs)
      @client = Client.new(**attrs)
    end

    def method_missing(method, *args)
      if client.respond_to?(method)
        ActiveSupport::Notifications.instrument("request.octokit", method: method) do
          client.public_send(method, *args)
        end
      else
        super
      end
    end
  end
end

Next, you need to setup ControllerRuntime to register to those events in an initializer, so they get tracked in your controller logs:

# config/initializers/controller_runtime.rb
ControllerRuntime.register(:octokit, label: "GitHub", event: "request.octokit")

Now you can use your custom client throughout your application and the time it takes to make a request will be tracked in your controller logs:

Completed 200 OK in 814ms (Views: 17.2ms | ActiveRecord: 0.0ms | GitHub: 734.1ms | Allocations: 191902)

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
