multiple databases on multiple instances
is a tough job. You need to monitor all these instances for everything. Best
way to keep eye on every instance activity is SQL Server Jobs.
Script to send an alert through mail, with
information that how many drive
space is required from next databases growth on a specific instance and how many
space is available.

How quickly databases on these instances are growing and
does target instance has 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.
space is required from next databases growth on a specific instance and how many
space is available.
