Problems using Modul logging with Blender

Hi,
there is a standard python module logging.
But I can not figure out how to use it correctly with Blender.
There are different logging levels.
logging.basicConfig(level=logging.Debug)
logging.critical(“Test”)
logging.error(“Test”)
logging.warning(“Test”)
logging.info(“Test”)
logging.debug(“Test”)
I think the first statement defines the level and all
messages should be shown in the Blender window.
But only the messages until warning level are be shown.
What is wrong?
Best Regards
Gerhard
