Troubleshooting

This guide walk you though the steps required to troubleshoot LibreTime.

Services status

When facing a problem with LibreTime the first reflex is to verify whether the services are running.

In the web interface, go to Settings > Status to see the state of the services.

If a service isn't running, you should search for details using the tool running those services. On a common setup, you should use the systemd service status:

sudo systemctl status libretime-celery

note

Be sure to replace the service name with the problematic one.

Logs

The next place to search for details on potential errors are the log files. On a common setup, you should search for the following files:

• /var/log/libretime/analyzer.log contains logs from the analyzer,
• /var/log/libretime/api.log contains logs from the api,
• /var/log/libretime/legacy.log contains logs from the legacy app,
• /var/log/libretime/liquidsoap.log contains logs from liquidsoap,
• /var/log/libretime/playout.log contains logs from playout.

For some LibreTime services, you can set a higher log level using the LIBRETIME_LOG_LEVEL environment variable, or by running the service by hand and using a command line flag:

sudo -u www-data libretime-analyzer --config /etc/airtime/airtime.conf --log-level debug

• /var/log/syslog contains most of the system logs combined. This log file may contain information that the application logger wasn't able to log, such as early startup errors. You can get the LibreTime logs using:

sudo tail -f "/var/log/syslog" | grep "libretime-"

• /var/log/apache2/error.log contains logs from the web server.
