In our Plesk panel on virtual and dedicated servers, we can configure the notification system to send emails to our clients, resellers, or ourselves to notify us of space, traffic, etc.
This way, we can automatically notify our clients that the contracted space is being exceeded or even ourselves to know the level of load on our machine.
To do this, we must first fill in our details in the Profile and Preferences section within My Profile.
Once completed with our information, we must follow the path: System Administration >> Tools and Settings >> Plesk >> Notifications.
