Centralized logging¶
OpenStack-Ansible configures all instances to send syslog data to a
container (or group of containers) running rsyslog. The rsyslog server
containers are specified in the log_hosts section of the
openstack_user_config.yml file.
The rsyslog server container(s) have logrotate installed and configured with a 14 day retention. All rotated logs are compressed by default.
Finding logs¶
Logs are accessible in multiple locations within an OpenStack-Ansible deployment:
- The rsyslog server container collects logs in
/var/log/log-storagewithin directories named after the container or physical host. - Each physical host has the logs from its service containers mounted at
/openstack/log/. - Each service container has its own logs stored at
/var/log/<service_name>.
