Account DNS Check
Checks to see if accounts on the server actually resolve to the server.
This plug-in gives administrators the ability to clean up their backup directory by setting how long they want to keep backups for accounts that no longer exist and removing those backups when they expire. The script can be run by hand or automatically after the cPanel backup script finishes.
This plugin gives administrators the ability to monitor concurrent user connections to MySQL. The WatchMySQL daemon can be configured so that when a user exceeds their connection limit a notification is sent to the administrator and/or user. The daemon can also be configured so that it will kill off those connections. Limits can be set per user, per package, or globally.
