Rack::Probe : dtrace probes for your webapp
status
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.
requirements
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.
gem dependencies
- rack
- ruby-dtrace
installing
gem sources -a http://gems.github.com

Rails Middleware:
Inside your config/environment.rb

config.middleware.use "Rack::Probe"
Rack Middleware:
Inside your rackup file
require 'rack/probe'
