Cpanel Database Soft Quotas
The file used to cache the number of databases owned by an account moved from /home/user/.cpanel/datastore/mysql-db-count to /var/cpanel/datastore/user/mysql-db-count. Likewise the PostgreSQL cache file is now /var/cpanel/datastore/user/postgres-db-count.
To keep the cache file current, a cron job executes the following command periodically: /scripts/update_db_cache.
cPanel™ 11.25 provides support for including the disk space consumed by an account’s MySQL and PostgreSQL database in the disk usage for the account. To enable this feature toggle the following Tweak Settings: When displaying disk usage in cPanel/WHM include Postgresql and MySQL® disk usage.

Rebuilding RRD Data Files
RRD files can be regenerated from the various summary files by using the /usr/local/cpanel/bin/rebuildbwrrd utility.
The utility can regenerate the data for a specific user or all users. This utility accepts the following parameters:
–all - Process all users on the system.
–dir={path} - Used to specify the location of the RRD summary files and where to create the new RRD files. If not specified, uses /var/cpanel/bandwidth.
–gid={#} - The number specified with this parameter is used to set the GID on any created files. If not specified, the program uses the GID of the existing data files.
prefix - The user or domain to process.
Cpanel Customer Contact feature
The Customer Contact feature replaces the Support Request system that exists in prior versions. Resellers may configure this feature to display contact details for support, billing and sales departments.
The feature retains the ability to allow contact submissions via email or external applications. A simplified branding editor in this interface allows the reseller to modify the cPanel™ interfaces used by this feature.
This feature is available to all resellers. Configuration and template data for each reseller is stored in the cpanelbranding directory in the reseller’s home directory.
For the root user this is /var/cpanel/cpanelbranding. Configuration data is stored in the contactinfo.yaml file while branding related changes are stored in one of the following:
contactinfo_include.html - Displays contact information in the Contact and Help cPanel™ interfaces
supportinfo_include.html - Displays a support request form in the Contact and Help cPanel™ interfaces.
Disk Space Usage and bandwidth data (RRD)
In cPanel™ 11.25 the number of bandwidth data (RRD) files has increased. File names have also changed for clarity. There are now two files for each protocol and for the aggregate.
As noted above, the number of RRD files generated by the system increased with cPanel™ 11.25. With this comes an increase in the disk space used by /var/cpanel/bandwidth.
To prevent issues related to disk consumption by the RRD files, during the cPanel™ Update /usr/local/cpanel/bin/chk_bwrrd_space is used to examine the disk mount that contains /var/cpanel/bandwidth.
If insufficient disk space is detected then bandwidth generation is disabled.
