SQL Server: Script to Generate HTML Report/mail for Databases Current Size, Growth Rate and Available Disk Space

• Download script

Working with multiple databases on multiple instances is a tough job. You need to monitor all these instances for everything. The best way to keep an eye on every instance activity is SQL Server Jobs.

How quickly databases on these instances are growing and does target instance have required space on hard drives? These are basic questions which every DBA keeps in mind during instance monitoring.

Amna Asif has suggested a better script to create a proper report (to mail) for actual database space, required and currently available on hard drives.

/*
 Script to send an alert through mail, with information that how much drive
 space is required from next databases growth on a specific instance and how much 
 space is available.
