Note: Watchdog is only available in Plesk for Linux, and is not available on Red Hat Enterprise Linux 9, AlmaLinux 9, Debian 11, and Ubuntu 20.04 and later.

Issue: When I stop a Plesk service, it starts automatically, and the component does not seem to work properly.

Resolution: Make sure you did not remove the Plesk event handlers that are required for the proper work of the component:

Service started lowest (0) psaadm /usr/local/psa/admin/bin/php /usr/local/psa/admin/bin/modules/watchdog/wd --monit-service=<new_service> --plesk-name
Service stopped lowest (0) psaadm /usr/local/psa/admin/bin/php /usr/local/psa/admin/bin/modules/watchdog/wd --unmonit-service=<new_service>

Note: If you use Debian Linux or Ubuntu Linux, the path to Watchdog’s system files is /opt/psa/admin/modules/watchdog/.

Issue: No alerts are delivered.

Resolution: Please check if the outgoing SMTP server settings you specified are correct.
