jruby-rack-metrics

This is a simple rack middleware that gathers metrics for the individual uri's served by the wrapped application. It uses Coda Hale's metrics library and thus requires jruby.

Usage

Install it e.g. with bundler by adding it to your Gemfile file:

source 'http://rubygems.org'
gem 'sinatra'
gem 'jruby-rack-metrics', '= 0.0.1', :git => "git://github.com/tomdz/jruby-rack-metrics.git"

and then run bundler:

$ bundle install

Now you can use it like so in a Sinatra app:

require 'rubygems'
require 'bundler/setup'
require 'sinatra'
require 'jruby-rack-metrics'

set :environment, :production
use JrubyRackMetrics::Monitor, { :app_name => "HelloWorld", :jmx_enabled => true }

get "/" do
  "Hello World"
end

Requirements

Requires Rack and JRuby. It also needs the core metrics library jar in the classpath (it doesn't bundle it at the moment).
