Currently I am only getting ActiveRecord and view-rendering output in my Rails application log file, since I switched to Puma from WEBrick. I haven't been able to find where I can modify the output level of Puma's logging. Thoughts?

Have you looked at the configuration.rb settings? It looks like you can send the standard error and out to a file. – erimar77 Feb 08 '15 at 20:16

From http://guides.rubyonrails.org/debugging_rails_applications.html#log-levels:
The available log levels are:
:debug
,:info
,:warn
,:error
,:fatal
, and:unknown
, corresponding to the log level numbers from 0 up to 5 respectively. To change the default log level, useconfig.log_level = :warn # In any environment initializer, or Rails.logger.level = 0 # at any time
This is useful when you want to log under development or staging, but you don't want to flood your production log with unnecessary information.
The default Rails log level is
debug
in all environments
