- Plesk for Linux
Disk usage at Subscriptions > example.com > Websites & Domains > View More Statistic page shows incorrect data for subdomains.
This is expected behavior: the disk space occupied by the content of subdomains and additional domains are included in the disk space usage calculated for the main domain.
The value of disk space usage calculated for a subdomain or additional domain includes only system files such as configurations and logs of the domain.
Currently, there is no such functionality in Plesk to see the statistics of a subdomain via the Plesk user interface.
