Home OpenStack-Ansible Installation Guide

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-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>.
