I wrote a blog post with a quick log file parser that might help you at  
[http://ramblingsonrails.com/a-rails-log-parser-to-show-how-your-actions-are-performing](http://ramblingsonrails.com/a-rails-log-parser-to-show-how-your-actions-are-performing)

If you’re working with rails, you could write a rake task and call that  
from  
cron or just run a ruby script directly like:

- 
  - 
    - 
      - 
        - /usr/bin/ruby /path/to/your/ruby/script.rb

If you’re running a Rake task, most of these will expect the root of  
your  
Rails project to be the current directory. Unless running in development  
you will also want to specify the environment:

m h \* \* \* (cd /path/to/project; RAILS\_ENV=production /usr/bin/rake  
my:task)
