Demo Rails application using AppFirst Statsd Gem

Here are the key points:

in Gemfile (assuming your development environment might be non-posix):

group :production do
  gem ‘posix_mq’, ‘~>2.0.0’
end
gem ‘afstatsd’

in config/application.rb:

#Statsd.logger ||= Logger.new 'afstatsd.log'   # uncomment to enable logging
#Statsd.logger.level = Logger::DEBUG           # 

$mystatsd = Statsd.new
$mystatsd.aggregating = false

Then with bundler:

bundle install --without production

Anywhere in your code:

$mystatsd.increment 'foo'                            # increment event counter 'foo'.
$mystatsd.decrement 'manchu'                         # decrement event counter 'manchu'.
$mystatsd.count 'mustache', 10                       # report that event 'mustache' occurred 10 times.
$mystatsd.gauge 'buffers_left', buffer_pool.count    # report a value as a guage
$mystatsd.time 'cart_process_time' {cart_processing} # will report the execution time of	a block
