Help me understand please. I'm new in python. I'm writing WSGI app. And I want to turn loggining on. I do:
logger = logging.getLogger(__name__)
then I want to print something in log:
logger.exception("Some exception...")
Where it all stores? Only in console output or there is a file somewhere on the server? If so, where I can find this file?
Actually, you have to specify the file yourself, e.g. with logging.basicConfig():
logging.basicConfig(filename="/path/to/your/logfile.log")
Logging can be quite a complex matter sometimes, I'd suggest you read the HOWTO.
import logging
logging.error("Error") # Prints to console
This how to write a log to a file
logging.basicConfig(filename='Error.log',level=logging.ERROR)
logging.error('Error')
Opening the Error.log you will see
ERROR:root:Error
More info here
logging.ERROR, which means nothing will get logged because a warning is less important than an error. Tichodroma's comment seems to refer to your calling warning() with a message consisting of Error. Indeed, in that case, you probably should call error() instead :)
