Comment 8 for bug 1285766

Another option is for savanna-api Openstack service, use log_config_append instead of log_config and correct
log_format=%(asctime)s.%(msecs)06d+00:00 savanna-api %(levelname)s: %(name)s: %(message)s
and log_date_format=%Y-%m-%dT%H:%M:%S
For example, patch for nova config could be http://pastebin.com/akN4J2EN. That would make all nova subservices to log locally as is, and remotely to /var/log/remote/node-baz.qux/nova.log
