How to turn off all Plesk Health Monitor alert emails
In order to disable the “alarm level changed” email notifications which are associated with the Health Monitoring module in Parallels Plesk, you need to disable the service from running and starting with your server.
To turn off the daemon that is responsible for sending these emails, issue this:
/etc/init.d/psa-health-monitor-notificationd stop
No more emails until you restart the server, when the daemon will be resumed. If you don’t want that, switch it off at boot time using
chkconfig psa-health-monitor-notificationd off
