Chapter 8. Automation controller logs

Automation controller logs are accessed in different ways depending on whether you have an RPM-based or containerized installation of Ansible Automation Platform.

Logs for containerized Ansible Automation Platform are not saved to specific files. The application logs are sent to the container stdout and handled by Podman with journald.

The three containers associated with automation controller are:

  • automation-controller-rsyslog
  • automation-controller-task
  • automation-controller-web

For more information about the purpose of each of these containers and how to inspect the logs, see Diagnosing the problem in Containerized installation.

Automation controller logfiles can be accessed from two centralized locations:

  • /var/log/tower/
  • /var/log/supervisor/

In the /var/log/tower/ directory, you can view logfiles captured by:

  • tower.log: Captures the log messages such as runtime errors that occur when the job is executed.
  • callback_receiver.log: Captures callback receiver logs that handles callback events when running ansible jobs.
  • dispatcher.log: Captures log messages for the automation controller dispatcher worker service.
  • job_lifecycle.log: Captures details of the job run, whether it is blocked, and what condition is blocking it.
  • management_playbooks.log: Captures the logs of management playbook runs, and isolated job runs such as copying the metadata.
  • rsyslog.err: Captures rsyslog errors authenticating with external logging services when sending logs to them.
  • task_system.log: Captures the logs of tasks that automation controller is running in the background, such as adding cluster instances and logs related to information gathering or processing for analytics.
  • tower_rbac_migrations.log: Captures the logs for rbac database migration or upgrade.
  • tower_system_tracking_migrations.log: Captures the logs of the controller system tracking migration or upgrade.
  • wsbroadcast.log: Captures the logs of websocket connections in the controller nodes.

In the /var/log/supervisor/ directory, you can view logfiles captured by:

  • awx-callback-receiver.log: Captures the log of callback receiver that handles callback events when running ansible jobs, managed by supervisord.
  • awx-daphne.log: Captures the logs of Websocket communication of WebUI.
  • awx-dispatcher.log: Captures the logs that occur when dispatching a task to an automation controller instance, such as when running a job.
  • awx-rsyslog.log: Captures the logs for the rsyslog service.
  • awx-uwsgi.log: Captures the logs related to uWSGI, which is an application server.
  • awx-wsbroadcast.log: Captures the logs of the websocket service that is used by automation controller.
  • failure-event-handler.stderr.log: Captures the standard errors for /usr/bin/failure-event-handler supervisord’s subprocess.
  • supervisord.log: Captures the logs related to supervisord itself.
  • wsrelay.log: Captures the communication logs within the websocket relay server.
  • ws_heartbeat.log: Captures the periodic checks on the health of services running on the host.
  • rsyslog_configurer.log: Captures rsyslog configuration activity associated with authenticating with external logging services.

The /var/log/supervisor/ directory includes stdout files for all services as well.

You can expect the following log paths to be generated by services used by automation controller (and Ansible Automation Platform):

  • /var/log/nginx/
  • /var/lib/pgsql/data/pg_log/
  • /var/log/redis/

Troubleshooting

Error logs can be found in the following locations:

  • Automation controller server errors are logged in /var/log/tower.
  • Supervisors logs can be found in /var/log/supervisor/.
  • Nginx web server errors are logged in the httpd error log.
  • Configure other automation controller logging needs in /etc/tower/conf.d/.
