Dynamically changing log level without restarting the application
fileConfig
is a mechanism to configure the log level for you based on a file; you can dynamically change it at any time in your program.
Call .setLevel()
on the logging object for which you want to change the log level. Usually you'd do that on the root:
logging.getLogger().setLevel(logging.DEBUG)
In addition to the accepted answer: Depending on how you initialized the logger, you might also have to update the logger's handlers:
import logging
level = logging.DEBUG
logger = logging.getLogger()
logger.setLevel(level)
for handler in logger.handlers:
handler.setLevel(level)
