Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

Started GET "/" for 127.0.0.1 at Mon Sep 06 01:07:11 -0400 2010

# You can use this class in your console. For example
#   p = ProfilingTools.new
#   p.profiled_request(:controller => :welcome, :action => :index)
# this will profile whole application stack and save file in your tmp/profiler folder
# You can also use +request+ method just to see the output for example:
#
#   p.request(:controller => :offers, :action => :index)
#   
#   p.response.body
#   p.response.cookies # and so on
