Comment 3 for bug 1290759

AFAICS, none of the services log anything at all by default in the seed/undercloud:

# ps ax | grep heat
 3687 ? Ss 0:01 /opt/stack/venvs/openstack/bin/python /opt/stack/venvs/openstack/bin/heat-api
 3699 ? Ss 0:01 /opt/stack/venvs/openstack/bin/python /opt/stack/venvs/openstack/bin/heat-api-cfn
 3709 ? Ss 0:01 /opt/stack/venvs/openstack/bin/python /opt/stack/venvs/openstack/bin/heat-api-cloudwatch
 3745 ? Ss 0:01 /opt/stack/venvs/openstack/bin/python /opt/stack/venvs/openstack/bin/heat-engine

# grep log_ /etc/heat/heat.conf
#default_log_levels=amqplib=WARN,sqlalchemy=WARN,boto=WARN,suds=INFO,keystone=INFO,eventlet.wsgi.server=WARN
#log_config=<None>
#log_format=<None>
#log_date_format=%Y-%m-%d %H:%M:%S
#log_file=<None>
#log_dir=<None>
#syslog_log_facility=LOG_USER

Because we don't set log_file, everything gets logged only to the console, which presumably means we don't log anything anywhere?
