Working with 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.
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.

Possibly you have database name with space or special characters. Script updated.
ReplyDeletegood work!!
ReplyDeletevery nice good work !!!!!!

ReplyDeleteD.V
Amazing Script..... Great Work.
ReplyDeleteThank you.
Aasim,
ReplyDeletecan we schedule a job like this to get us the report for all production server in one email itself?
Excellent script for monitoring database size, I want to know as output required drive space 218.67 MB?
ReplyDeleteAs of now E drive 1.01 TB Free space available of Total 1.09 TB
Pl. explain
ananda, Thanks your appreciations. Can you please share complete result (html) (please share it through mail), so we can figure out what's missing.
DeleteRow ID Drive Drive Space Required Drive Space
Delete1 C 78510 MB 0

what does it means? required drive space 144.97 MB, does it next data growth size?
I get this error for some of the larger databases. The error is in the INSERT INTO #ServerFileStats subquery.
ReplyDeleteArithmetic overflow error converting expression to data type int.
Any idea ?
Change all INT parameters to BIGINT
DeleteHello,
ReplyDeleteUsing MSSQL 2005, we have problems with your script.
These were causing errors, in order : SYSNAME (replaced by sysname), SYS.DATABASES (replaced by sys.databases), and Drive (Invalid column name 'Drive'.) for this one we can't find the root cause.
Can you please help us ?
thanks in advance.
Hi Assim, This is very awasome script. Thanks for sharing it.
