Hi George Rails' ActiveSupport overrides the Logger#format_message method. To get back to the normal log formatting, you can use something like this in you script. class Logger private # Rails overrides this method so that it can customize the format # of it's logs. def format_message(*args) old_format_message(*args) end end Which is a bit hacky maybe, but it's working for me at the moment. Hope this helps.
