I know it’s quite a dummy question but cannot figure it out my self:
I have a Rails server running on Passenger Nginx.
I notice that there is 3 logs file that may be related:
$app/current/logs/production.log and $nginx/logs/access.log and $nginx/logs/error.log.
Recently my app encounter an errors. I expect the error being dumped to either of the 3 files above. But in fact, when I looked at them, none contains the error. The production.log contains nothing except the assets compilation output. The access.log and error.log contains just very basic logging from nginx itself.

I didn’t customize anything about Rails.logger in my app.

What I am missing? Where can I look for the app error now?

    Josh, it’s turn out to be a recent issue of Rails (3.2.1 which I’m running on).
    There is a fix suggested by @babatakao (as specified on https://github.com/rails/rails/issues/4277):

    Rails.logger.instance_variable_get(:@logger).instance_variable_get(:@log_dest).sync = true if Rails.logger
