Could someone point me to the valid values for log\_level? I can’t find  
anything but :debug and :info.

I’m trying to turn off logging of the params values. Is that possible?  
Or do I have to turn off logging of the request / response altogether?  
I assume I could to that pointing the log to /dev/null. Yes?

Thanks,  
Bill

This might be a little more than what you’re asking - but the  
customizations look to be just the ticket:

Thanks much for your reply. I’d read through that already article and  
was  
hoping there might be another setting for the default logger that I just  
didn’t know about. I’m not sure what my hosting service will let me do  
wrt  
changing the logger.

Best regards,  
Bill

In addition to Jodi’s answer, you might also have a look at  
ActionController::Base.filter\_parameter\_logging method  
to filter params values.

See :

Logging is important, you shouldn’t disable it completely imho.

Thank you very much for that. I hadn’t discovered that method before  
and,  
with a little experimenting, it may be just the thing. I really don’t  
want  
to turn off logging; just get rid of the params values in the log.

Best regards,  
Bill

My bad on two counts. 1) the logger is in Ruby, not Rails. 2) the  
article  
had a link to the Ruby doc on logger. The answer my question about  
valid  
logging levels is at [http://www.ruby-doc.org/stdlib/libdoc/logger/rdoc/](http://www.ruby-doc.org/stdlib/libdoc/logger/rdoc/)

hth someone in the future.
