How to adjust the logging level #564
Description
I am using CoreEmu as an API for python tests and I am noticing a lot logging, such as this:
INFO:root:emane is not installed
INFO:root:created session: 1
INFO:root:opening xml: 1_multiple_links.xml
INFO:root:changing session(1) to state CONFIGURATION_STATE

...
And on and on.
I am trying to set the logging level to warning only for core here:
import logging
from core.emulator.coreemu import CoreEmu
logging.getLogger('core').setLevel(logging.WARNING) #I also tried 'CoreEmu' and a few other combinations to no affect.
logging.getLogger().setLevel(logging.INFO)
logging.basicConfig(format='%(asctime)s,%(msecs)d %(levelname)-8s [%(filename)s:%(lineno)d] %(message)s',
datefmt=TIME_FORMAT, level=logging.INFO)But I am not seeing any affect. It seems almost that the core is logging straight to root?
I am wondering if there is a best way to ensure the log messages generated within the Core/CoreEmu libraries, I can set it to logging.WARNING.
We are using Core 6.3.0. I know it is multiple versions behind, we are planning to upgrade however until then, hopefully the mechanism for adjusting the logging level is the same regardless.
