title: need help configuring rails4 logs
body: <p>I'd like to analyze the logs of a rails4 app we're working with - using request-log-analyzer - and so far </p>

  <p>it skips all lines.  The only change I've made in the config for logging is to prefix a subdomain (config.log_tags = [ :subdomain ] in app/environments/production.rb).  I tried removing it, though, and still no parsing.<br>
  An example of the way the log files look is below, and I'm using this command to parse them: request-log-analyzer --parse-strategy assume-correct --format rails --file o production.log.  FYI running with puma and nginx.  </p>
  
  <p>Does anyone know what I have to do to get the logs in shape for request-log-analyzer to parse them?</p>
