Doesn't log anything on production

[johnnncodes]

For some reason it doesn't log anything on our production environment but it works fine on development environment. These are the lines that I added on both /config/environment/production.rb and /config/environment/development.rb:

  config.rails_semantic_logger.add_file_appender = false # disable logging to a file
  config.after_initialize do
    config.semantic_logger.add_appender(appender: :syslog, formatter: :json)
  end

It logs the active record queries in our rake tasks though. Any ideas on what I'm doing wrong?

Rails 4.2.6

rails_semantic_logger (3.4.1)
semantic_logger (~> 3.3)

Closing this issue now... I'm using unicorn and I think I need to do this to make it work: http://rocketjob.github.io/semantic_logger/forking.html
