I am a relative newbie to Python and its logging infrastructure;
however, I have programmed extensively with Java/C# and log4j and
log4net. That, I suppose, could be the root of my problem :)
I am trying to setup one logger per module (as this is roughly
analogous to how I've used log4j/log4net). However, I've noticed that
my loggers have the disabled flag set to true (more accurately, 1)
when they are initialized. For each logger, do I have to force
disabled = False? To make this more concrete, here is an example.
In example.py:
import logging
import logging.config
_log = logging.getLogger("prediction.predict")
def main():
logging.config.fileConfig('logconfig.conf')
_log.warn("test warning!")
if __name__ == "__main__":
main()
Unfortunately, this does not print out "test warning!" and if I put a
breakpoint at the _log.warn("test warning!") line, _log.disabled
equals 1. If I change main to:
def main():
logging.config.fileConfig('predict_logconfig.conf' )
_log.disabled = False
_log.warn("test warning!")
It works! So, am I doing something wrong or do I always have to force
my loggers to be enabled? Should I update my configuration file so
that loggers start as enabled? Here is my config file
(logconfig.conf):
