Specifically within the dreamhost environment (fastcgi)? (that’s the  
only place I’ve attempted deploying out to).

I’ve placed a few logger.debug statements in my application but don’t  
see them popping up anywhere - production.log, error.log … and I  
have no idea where it might be going out to?

Or should I use something like logger.error?

thanks for the help!

just tracked something down that said to try logger.warn and that  
seems to be doing the trick.

carry on 🙂

Rails uses built-in Ruby Logger class and sets logging level based on  
running environment.

INFO for production and DEBUG for all other environments.

As you can see from the Ruby documentation, the order of levels is  
FATAL, ERROR, WARN, INFO, DEBUG and logger only logs messages in lower  
levels, so it doesn’t log debug messages when the level is INFO.

Look here for more info:
