== About

Action Profiler allows you to profile a single Rails action to  
determine what  
to optimize. You can use the Production Log Analyzer and action\_grep to  
determine which actions you should profile and what arguments to use.

Information on the Production Log Analyzer can be found at:

[http://rails-analyzer.rubyforge.org/pl\_analyze](http://rails-analyzer.rubyforge.org/pl_analyze)

=== Profilers

Action Profiler REQUIRES Ruby 1.8.3, even if you just use Ruby’s builtin  
profiler.

Action Profiler can use three profilers, Ruby’s builtin profiler class,  
Shugo M.‘s Prof or Ryan D.’ ZenProfile.

Shugo M.'s Prof: [http://raa.ruby-lang.org/project/ruby-prof](http://raa.ruby-lang.org/project/ruby-prof)

Ryan D.’ ZenProfile: [http://rubyforge.org/frs/](http://rubyforge.org/frs/)?  
group\_id=712&release\_id=2476

=== Running Action Profiler

Typically, action\_profiler will be run from the root of your Rails  
application:

$ action\_profiler GamesController#index  
Warmup…  
Profiling…  
[profile output]  
$

If you need to run action\_profiler from some other path, the -p  
command line  
option can be used to specify the location of your Rails application.

action\_profiler -p ~/Worx/X/CCR GamesController#index

Parameters can be specified after the controller and action:

action\_profiler GamesController#index “:id =\> 1”

If you need to make sure a page is working correctly you can specify -  
o. No  
profiling will occur and the generated page will be printed out instead:

$ action\_profiler -o GamesController#show “:id =\> 1”  
[lots of HTML output]  
$

== Gem Installation

gem install action\_profiler
