Understand Resources in Plesk

Resources

Resources (located at Service Plans > select a plan > Resources tab) define what system resources are provided with the subscription.

Overuse policy

Defines what happens if the subscription’s usage of disk space and traffic reaches limit values:

  • Overuse is not allowed will suspend the subscription.

  • Overuse of disk space and traffic is allowed will let the subscription operate properly if disk space and traffic are overused.

    You can select Notify me by email in cases of overuse to notify users as soon as disk space or traffic usage exceeds the specified limit (the Notify when disk space usage reaches and Notify when traffic usage reaches options). The notifications will be sent to the users or email addresses specified at Tools & Settings > NotificationsResource usage limits exceeded by subscription.

  • Overuse is allowed will let the subscription operate properly when any types of resources are overused.

    You can select Notify me by email in cases of overuse to notify users as soon as any resource is overused. The notifications will be sent to the users or email addresses specified at Tools & Settings > NotificationsResource usage limits exceeded by subscription.

Note: The overuse policy does not apply to the limits set on the size of mailboxes. Therefore, even if you enable overuse, be sure to allocate enough disk space to mailboxes.

Disk space
The total amount of disk space allocated to the subscription. It includes disk space occupied by all files related to the subscription: the content of websites, databases, applications, mailboxes, log files and backup files.

Notify when disk space usage reaches
Available only if overuse of disk space and traffic is allowed. This sets the notification limit for disk space usage. When this limit is reached, Plesk sends notifications to users’ email addresses specified in Tools & Settings > Notifications: Resource usage limits exceeded by subscription.

Note: The notification limit can be set in MB/GB/TB or in percent. If the limit should be persistent, you can specify it in MB/GB/TB (in this case, after you add an add-on that enhances disk space for the subscription, this limit remains unchanged). If the notification limit should be floating, you can specify it in percent (in this case, after an add-on is added, the limit will be automatically recalculated). For example, if you have disk space = 10Gb, set a notification limit = 9Gb and add an add-on with 5 Gb of disk space, notification will be sent after 9Gb is exceeded. And if in the same case you set a notification limit = 90%, notification will be sent after 13.5Gb is exceeded.

Traffic
The amount of data that can be transferred from the subscription’s websites and FTP/Samba shares during a month.
