I have previously described how to adjust the values that the Plesk Health Monitor uses to determine when an email should be sent out.
There is also a way to switch these emails off entirely. Here’s how:
To turn off the daemon that is responsible for sending these emails, issue this:
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
To remove the Health Monitor altogether, head over to Tools and Settings – Updates and Upgrades and uninstall the component.
