Trashed

Keep an eye on resource usage.

• Logs per-request object counts, heap growth, and GC time.
• Sends periodic resource usage snapshots to StatsD & NewRelic.
• Requires Ruby 1.9 or REE.

Setup

Rails 3

On Rails 3, add this to the top of config/application.rb:

require 'trashed/railtie'

And in the body of your app config:

module YourApp
  class Application < Rails::Application
    config.trashed[:statsd] = YourApp.statsd

Rails 2

On Rails 2, add the middleware to config/environment.rb:

Rails::Initializer.run do |config|
  config.middleware.use Trashed::Rack::MeasureResourceUsage, :statsd => YourApp.statsd

And set up the sampler in config/initializers/trashed.rb:

Trashed::Newrelic.sample Trashed::ResourceUsage, :statsd => YourApp.statsd
