title: Logging in Ruby on Rails in Production Mode
body: <p>I would like to view some variables in controller, it tried the following:</p>
  
  <p><code>Rails.logger.debug "Year: #{Time.now.year}"</code></p>
  
  <p><code>puts "Year: #{Time.now.year}, Month: #{@month}"</code></p>
  
  <p>where can I see the output for Logger or Puts in production mode?  Do I need so set something up to view these somewhere?</p>
