Thoughts About Rails Presenters

Thoughts about Rails Presenters

This is a collection of links, examples and rants about Presenters/Decorators in Rails.

Jay Fields wrote about it in 2007 (before he switched back to Java and then Clojure):

somebox / unicorn-graphite.rb
Created Nov 12, 2013
Graphing unicorn active/queued processes (via sockets)
View unicorn-graphite.rb
#!/usr/bin/env ruby
require 'rubygems'
require 'raindrops'
require 'statsd'
# This script monitors the active and queued unicorn processes.
# It uses the raindrops gem to look at the unix domain socket.
# Stats are polled every second (for one minute) and pushed to
# statsd as a counter. This script runs once a minute.
