Hi, Misleading wording: https://docs.python.org/2/howto/logging.html#logging-advanced-tutorial Section ->Basic Logging Tutorial->When to use logging-> ... The default level is WARNING, which means that only events of this *level and above* will be tracked, unless the logging package is configured to do otherwise. ... But based on the table before this sting: Level When it’s used DEBUG Detailed information, typically of interest only when diagnosing problems. INFO Confirmation that things are working as expected. WARNING An indication that something unexpected happened, or indicative of some problem in the near future (e.g. ‘disk space low’). The software is still working as expected. ERROR Due to a more serious problem, the software has not been able to perform some function. CRITICAL A serious error, indicating that the program itself may be unable to continue running. So according to statement, all above which are blue will be logged. Which is not true. With WARNING level it will log: WARNING, ERROR, CRITICAL. As show in *A simple example* section in https://docs.python.org/2/howto/logging.html#logging-advanced-tutorial Does this make sense? Or I didn't read it properly? Sincerely, -Slava
