Steps to get Rails 4 saving its output to Syslog via Rsyslog. This assumes you are on CentOS, but should be pretty adaptable to any other distribution. Ruby 2.0+ is also required.

1. Add the gems lograge and logstash-event to your Gemfile. Feel free to remove from production if you'd like to test it in development as well or something.
2. Update production.rb with the lograge settings and set the logger to Syslog::Logger.
3. Add the conf files to /etc/rsyslog.d/. /etc/rsyslog.conf should have $IncludeConfig /etc/rsyslog.d/*.conf enabled, so it will load any additional configs from /etc/rsyslog.conf.
