Is there a simple way to customize logging so that when you call the  
logger method it includes the severity in the log? I just want to  
make it easy to find with something like a GREP.

So a call to this:  
logger.warn(‘my message’)

Would put this in the log:  
WARNING: My message

Thanks,  
Tom

Just create a custom formatter and reference the log level there.  
Something like the following, warning this has not been tested.

class Logger  
def format\_message(severity, timestamp, progname, msg)  
“#{RAILS\_DEFAULT\_LOGGER.level} #{timestamp} (#{$$}) #{msg}\n”  
end  
end
