Hi All, I have observed that devstack uses custom logging formatting that differs from the documented defaults. An example is for nova. logging_context_format_string = %(asctime)s.%(msecs)03d %(levelname)s %(name)s [%(request_id)s *%(user_name)s %(project_name)s*] %(instance)s%(message)s which is defined in [1] , compared with logging_context_format_string = %(asctime)s.%(msecs)03d %(levelname)s %(name)s [%(request_id)s *%(user_identity)s*] %(instance)s%(message)s which is the current Liberty specified default [2]. This infact is the Oslo Logging default value and then can effectively be not defined at all. In my manual tests I see not see failures when changing this in nova, but as I know Infra and QA relies on devstack I would like to solicit feedback from team members before proposing any changes to bring these to being consistent. This logging variable is also defined differently across 4 projects (nova, cinder, keystone and glance) so ultimately the goal would be to ensure they may present documented configuration defaults.
