`Home <index.html>`_ OpenStack-Ansible Installation Guide
Centralized Logging
-------------------
OpenStack-Ansible will configure 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-storage`` within
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>``
