Hello, I have a machine on which openstack runs and it uses stevedore API, see for example: https://github.com/openstack/stevedore/blob/master/stevedore/extension.py My question is: In the exension.py file of stevedore, there are loggin messages, like ... LOG.debug('found extension %r', ep) ... What is the location of the log file to which these messages are written ? Regards, Kevin
