Rack::Probe (along with Dtracy) is part of the Ruby on Rail's Google Summer of Code '09 Quartet, with development updates and entertainment available at http://ecin.tumblr.com Welcome! Sit down, grab a sugary drink, and enjoy the smell of freshly baked code right out of the oven.
An operating system with support for Dtrace (http://www.sun.com/bigadmin/content/dtrace/) is a must. Mac OS X, Solaris/OpenSolaris and FreeBSD are all acceptable choices, though no testing has been done on FreeBSD.

Rails Middleware:
Inside your config/environment.rb
config.gem "kevinykchan-rack-probe", :lib => "rack/probe"
config.middleware.use "Rack::Probe"
Rack Middleware:
Inside your rackup file
require 'rack/probe'
use Rack::Probe
From a terminal, run dtrace -n rack*::: -l to get a list of all the available probes. The number you'll see after 'rack' in the provider field is the PID of the process that's making the probes available.
