Hi there!
I installed a fresh Plesk Onyx on Ubuntu 16.04, and ran into problems with Watchdog. Spamassassin and PHP-FPM were reported as down and eventually released from monitoring.
I tried uninstalling and reinstalling Watchdog, to no avail.
I then had a look at /usr/local/psa/etc/modules/watchdog/monitrc.tpl to find out that the pid files the config points to do not exist.
To avoid fiddling with the Watchdog config, i issued ln -s plesk-php70-fpm.pid php5-fpm.pid and ln -s spamassassin.pid spamd.pid, now they show as online.
