How to use logging with python's fileConfig and configure the logfile filename

I have a logging configuration file for logging to console and a file with different formats and levels. In my python script I can load this configuration and basically console and file output are ok.

I set the file name in the config file as shown below.

Is it possible to set that file name in the python script itself?

python code:

# set up logging
logging.config.fileConfig(loginipath)
logger = logging.getLogger('sLogger')

# log something
logger.debug('debug message')
logger.info('info message')
logger.warn('warn message')
logger.error('error message')
logger.critical('critical message')

logging config file:

[loggers]
keys=root,sLogger

[handlers]
keys=consoleHandler,fileHandler

[formatters]
keys=fileFormatter,consoleFormatter

[logger_root]
level=DEBUG
handlers=consoleHandler

[logger_sLogger]
level=DEBUG
handlers=consoleHandler,fileHandler
qualname=sLogger
propagate=0

[handler_consoleHandler]
class=StreamHandler
level=WARNING
formatter=consoleFormatter
args=(sys.stdout,)

[handler_fileHandler]
class=FileHandler
level=DEBUG
formatter=fileFormatter
args=('logfile.log',)

[formatter_fileFormatter]
format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
datefmt=

[formatter_consoleFormatter]
format=%(levelname)s - %(message)s
datefmt=

Change your handler_fileHandler section like so:

[handler_fileHandler]
class=FileHandler
level=DEBUG
formatter=fileFormatter
args=('%(logfilename)s',)

and then add a defaults argument to the fileConfig call

logging.config.fileConfig(loginipath, defaults={'logfilename': '/var/log/mylog.log'})

Both handlers worked for me:

(1)

logging.config.fileConfig( 'logging.ini' , disable_existing_loggers=False)


[handler_myhandler1]
class=FileHandler
level=DEBUG
formatter=form01
args=('python.log', 'w')

(2)

logging.config.fileConfig( 'logging.ini' , disable_existing_loggers=False, defaults={ 'logfilename' : getSomeName() } )

[handler_myhandler2]
class=FileHandler
level=DEBUG
formatter=form01
args=('%(logfilename)s','w')
