Are you trying to log .. Concurrently with the Rails log, or are you 
trying to replace the default Rails logger with your own?
Look at this :

Keeping this in mind:
One important point to remember is that the logfile object does not 
implicitly flush to the file by default. This means that your code must 
call logfile.flush for the data to be written out. Alternatively, you 
can set logfile.sync = true to turn on implicit flushing.
