Stack traces are not captured by syslog by default

[Dmitry Borodaenko]

Default logging configuration in Fuel omits stack traces of OpenStack services: the log level is set to INFO while stack traces are logged at TRACE level. I think default configuration should include stack traces: if the cluster is ok, there is no increase to the log size, and if the cluster has a problem, there's no reason not to want the stack traces.

This is important for support reason, so increasing this bug to High level.

Note: for use_syslog and verbose, heat and neutron do provide TRACE level messages, other services don't. Need to investigate related configuration options and provide them by puppet manifests as well.

[Bogdan Dobrelya (bogdando)]

Investigation had shown the issue is related to the obsolete log_config option usage for OS configration and would be resolved once 2nd part of https://blueprints.launchpad.net/fuel/+spec/refactor-logging-puppet-openstack-services will be implemented

[Bogdan Dobrelya (bogdando)]

Stack TRACEs are usefull mostly for dev/QA teams, and not so much for customers or users. I set the status as a medium.
