Finding it in cPanel.
LISTING YOUR DATABASES
cPanel > MySQL Databases. It shows every database on the account, its size, and which users have access.
FINDING WHICH ONE A SITE USES
Read the site's configuration file. The database name is there.
With several sites on one account, this is the only reliable way to tell which database belongs to which site.
Record it somewhere. During an incident you do not want to be working it out.
THE SIZE COLUMN
Useful for spotting a database that has grown unexpectedly, which usually means bloat rather than content.
DATABASE USERS
Listed separately. A user is not a database; it is an account permitted to access one.
A database with no user assigned cannot be reached by anything.
WHAT COUNTS AGAINST YOUR PLAN
Most plans limit the number of databases. Check the statistics panel.
An account at its limit cannot create another, and installers fail without explaining that clearly.
OLD DATABASES
Accounts accumulate databases from applications long since removed. Review occasionally.
