Start of Authority (SOA) record
The SOA record is the first record in a properly configured zone. It contains information about the zone in a string of fields. An SOA record tells the server to be authoritative for the zone. The SOA record takes the format.
Example:
domain.name. IN SOA hostname.domain.name. mailbox.domain.name
serial-number
refresh
retry
expire
minimum-ttl
domain.name - The name of the domain to which the SOA belongs. Instead of writing out the full domain, you can also use ‘@’ in the file to let the nameserver fill this out automatically.
IN - The class of the DNS record. ‘IN’ is an abbreviated form of ‘Internet’.
SOA - The type of DNS record, which in this case is ‘Start of Authority’.
hostname.domain.name - Also known as the ‘hostmaster’ field. It contains the e-mail address of the person responsible for maintaining the zone.
minimum-ttl - The default TTL (Time To Live) for every record in the zone. The default is only used when a particular resource record does not have its own specified TTL value. When changes are being made to a zone, the default is often set at ten minutes or less.

Cpanel disk space consumed by an account’s MySQL and PostgreSQL database
To enable this feature toggle the following Tweak Setting:
When displaying disk usage in cPanel/WHM include Postgresql and MySQL® disk usage.
As with the database counts, the disk usage calculation is handled by /scripts/update_db_cache which executes every 4 hours. This script is executed upon enabling the Tweak Setting. Administrators may also execute this script to recalculate the figures.
The disk usage figures are stored in /var/cpanel/datastore/mysql-disk-usage and /var/cpanel/datastore/postgres-disk-usage.
cat /var/cpanel/datastore/mysql-disk-usage
Support for /scripts/updatemysqlquota ends as of cPanelTM 11.25.0. Per this change /scripts/updatemysqlquota is no longer distributed with the product.

Cpanel failurls File
The failurls file, located at /var/cpanel/failurls, allows you to specify where resellers can redirect users who fail to authenticate with cPanel.
Enter the URLs to which resellers can redirect users, one per line, in the file.
Entries in this file must meet the following requirements:
Entries must be an exact match. Dynamic URLs are not acceptable.
Example:
http://example.com/index.php?failed=1
Dynamic content on the login page must be passed via hidden POST variables. Using the GET query string will fail because it will not match any entry in the failurls file exactly. When you are finished creating entries in the failurls file, you must restart cPanel. To restart cPanel, run the following command as the root user:
/usr/local/cpanel/startup
