Python logging multiple files using the same logger

Question

This is my scenario: I want to log my_module\'s activity. This needs to be done, depending on the method executed (let\'s say, INPUT and OUTPUT), to two different files.

Answer 1

Finally I decided to define two loggers, because:

• They are for different purposses. In my case, one logs input request to a web service, and the other one logs the response. And they use different files to it

• I'm using a logging config file, in a frontal web service. Adding/removing handlers before logging messages is not the right approach, as @mike said. Thx to @drekyn too!

Here is my logging config file, just for reference if anyone is interested in:

[loggers]
keys=root, ws_in_log, ws_out_log

[handlers]
keys=consoleHandler, ws_in_hand, ws_out_hand

[formatters]
keys=generic_form

[logger_root]
handlers=consoleHandler
level=NOTSET

[logger_ws_in_log]
level=NOTSET
handlers=ws_in_hand
qualname=ws_in_log

[logger_ws_out_log]
level=NOTSET
handlers=ws_out_hand
qualname=ws_out_log

[handler_ws_in_hand]
class=logging.handlers.TimedRotatingFileHandler
level=NOTSET
formatter=generic_form
args=('/path/ws_in_.log', 'h', 1, 0, None, False, True)

[handler_ws_out_hand]
class=logging.handlers.TimedRotatingFileHandler
level=NOTSET
formatter=generic_form
args=('/path/em/ws_out_.log', 'h', 1, 0, None, False, True)

[handler_consoleHandler]
class=StreamHandler
level=DEBUG
formatter=generic_form
args=(sys.stdout,)

[formatter_generic_form]
format='%(asctime)s - %(levelname)s - %(message)s'
datefmt='%Y-%m-%d %H:%M:%S'
class=

See you!
