How is the log directory changed in nova without writing to a single file?

Running Mitaka, with nova/cinder/glance/neutron/horizon all on a single node (call it PoC, working out kinks in a lab setting). I'm working on setting up a log repo, and thought it would be helpful to have all openstack logs in /var/log/openstack, rather than /var/log/%service%/.

I created /var/log/openstack, assigned group ownership to 'openstack', and added service user accounts to that group.

In nova.conf, if I set log_dir = /var/log/openstack, the logs continue to write to their old address, with no complaints in any of the logs I can find. Am I misunderstanding the way this config option is to be used?

If I set log_file = /var/log/openstack/nova-api.log, every service that runs under nova writes to that single file.

It looks like I can use syslog, by using log_config_append to point to logging.conf, specify in that to send everything to syslog, and then setting a custom syslog conf specific for each service, but that seems like a really round-about way of doing it. Am I missing something obvious?

I think ,configure this section in /etc/nova/nova.conf :

Appreciate the answer; but the lock path is not the same as the log path. The lock path is for situations where you have two processes running parallel, they will check for a lock to ensure they aren't accessing the same file / resource at the same time.

sorry, this time will be right: in file /etc/nova/nova.conf


log_file = /var/log/nova/nova.log

then restart your nova-... services.
