A fork of trashed focused on Ruby metrics for Heroku.

On Rails 6 (and Rails 3 and 4 and 5), add this to your Gemfile:

gem "barnes"

Then run:

$ bundle install

Add the gem to the Gemfile

gem "barnes"

Then run:

$ bundle install

In your puma.rb file:

require 'barnes'

Then you'll need to start the client with default values:

before_fork do
  # worker configuration
  Barnes.start
end
