How disk usage is calculated by Plesk

Question

How disk usage is calculated by Plesk?

Answer

Note: Disk usage displayed in Plesk is updated once a day during the Plesk daily maintenance task. 

The disk usage is displayed on the domains Statistics page:

Power User view:

• Plesk > Statistics

Service Provider view:

• Plesk > Subscriptions > example.com > View More Statistics (Under Hosting)

 

These values are stored in the Plesk database in bytes (in binary).

1. Find the subscription id:

   # plesk db “select id,name from domains where name=’example.com'”
   +—-+————-+
   | id | name        |
   +—-+————-+
   | 3  | example.com |
   +—-+————-+

2. Find its overall disk usage:

   # plesk db “SELECT SUM(real_size) FROM domains d WHERE d.id=3“
   +—————-+
   | SUM(real_size) |
   +—————-+
   | 59314176       |
   +—————-+

 

Overall disk usage is divided into four groups of services:

• Web (httpdocs, subdomains, web_users and all other data, not included in Mail, Databases, Other)
• Mail (mailboxes, maillists)
• Databases (dbases)
• Other (anonftp, logs, domaindumps, configs, chroot)

 

Information about the size of these four services is stored in the “disk_usage” table of the psa database. Run the following command to get them:

# plesk db “SELECT SUM(httpdocs) + SUM(httpsdocs) + SUM(subdomains) + SUM(web_users) AS Web, 0 + SUM(mailboxes) + SUM(maillists) AS Mail, 0 + SUM(dbases) AS ‘Databases’, SUM(anonftp) + SUM(logs) + SUM(domaindumps) + SUM(configs) + SUM(chroot) AS Other FROM disk_usage AS disk_usage INNER JOIN domains AS domains ON domains.id = disk_usage.dom_id WHERE dom_id=3;”
+——–+——–+———–+——–+
| Web    | Mail   | Databases | Other  |
+——–+——–+———–+——–+
| 856064 | 143360 | 58150912  | 163840 |
+——–+——–+———–+——–+
