https://docs.python.org/3/library/logging.handlers.html#module-logging.handlers

14.7.1. BaseRotatingHandler¶

logging.handlers.BaseRotatingHandler

is the base class for handlers that rotate log files at a certain point. It is not meant to be instantiated directly. Instead, use RotatingFileHandler or TimedRotatingFileHandler.

14.7.2. RotatingFileHandler¶

logging.handlers.RotatingFileHandler

instances send messages to disk files, with support for maximum log file sizes and log file rotation.

14.7.3. TimedRotatingFileHandler¶

logging.handlers.TimedRotatingFileHandler

instances send messages to disk files, rotating the log file at certain timed intervals.

14.7.4. Example¶

>>> from logging.handlers import TimedRotatingFileHandler
>>> from logging import Formatter
>>>
>>> handler = TimedRotatingFileHandler(filename='/tmp/myfile.log', when='midnight')
>>> formatter = Formatter('%(asctime)s, %(levelname)s, %(message)s', datefmt='%Y-%m-%d, %H:%M:%S')
>>> handler.setFormatter(formatter)
