Good day,

I'd like to monitor the growth of our databases and watch for trends, make sure we don't run out of space, etc.

sp_spaceused is inaccurate unless you run dbcc updateusage and I've got many databases that are either too big or I don't have the window, etc... I've looked at the sysfiles system table but that gives you the "allocated" size of the file not the actual size.

I am specifically targeting 2000 boxes, since according to BOL in 2005 dbcc updateusage is unnecessary so long as the database was created in 2005 (versus upgraded to 2005).

So, my question is how are you all monitoring your db growth?

Thanks!

I used to monitor backup size quite a bit. It told me if data was growing a lot, and that's all I care about. Knowing if things are changing and how much space I need to add every xxx days.

Thanks for the reply Steve.

It appears sp_helpdb returns the "allocated" size, just like the sysfiles table. I've never peeked at the backup tables, I can do that, but it just seems like there's got to be a better way.

I love the .NET SMO libraries that come with 2005, but under the hood that must use sp_spaceused since the results are inaccurate for my 2000 boxes (until I run dbcc updateusage).

I should have updated that article. I looked through it after I posted, and realized that I had some VBScript scripts there looked at sizes of actual backup files.

These provided a good idea of how much data I had, and then if there was a change. If I captured that info, inserted it into a table and then ran a comparison day to day, I could easily see how much data I had, and how it was growing.

Henry..

Check my post out.. I write this script specially for this purpose.

Thanks for the suggestion IT.

Interesting script, I was not aware of DBCC SHOWFILESTATS. I do wonder, though, if it has the same shortcomings as sp_spaceused - meaning you first must run DBCC UPDATEUSAGE to get accurate results.

We have few 2000 machines left, so I'm not sure I'm going to spend any time on this but if I get a chance to test, I'll post back.

Thanks again.

Forgot to mention... the following comes with no warranties or guarantee that it wont totally mess things up... but it works great for me.

I am using various scripts and jobs to track growth and other capacity information on both SQL 2000 and 2005 databases. Almost all of this was taken from various scripts here and there (many from this very forum)... I wish I had tracked everyone whose code is included here so I could credit each of them.

It tracks and reports on the following:

-version, service pack, servername
- memory and load informatoin
- I/O stats over time
-average and max connections per database
-top wait types
-current disk space usage
-disk usage rate over time
-current datafile size and usages
-datafile growth rate over time
-total growth rate of datafiles over time
-current transaction log size and space used
-most recent backup time for each db
-databases where backups are over 24 hours old
-top queries by elapsed time (this is reported for sql 2005 only)

Here is what I am doing:

Before running this, you need a database called DXDBA. Dont just copy and paste the whole thing below, you need to do it step by step. Also for the queries that generate the report, if you do "results to text" it looks very readable.

PART 1: Capturing disk space information

1.) Create a table to hold disk space information:

USE [DXDBA]

CREATE TABLE [dbo].[Capacity_DiskSpaceTracking](
[ID] [int] IDENTITY(1,1) NOT NULL,
[TimeCollected] [smalldatetime] NOT NULL CONSTRAINT [Capacity_DiskSpaceTracking_TimeCollected] DEFAULT (getdate()),
DriveLetter CHAR(1)
, TotalSpace bigint
, FreeSpace bigint
, Label varchar(10)

) ON [PRIMARY]

2.) Create a procedure to write disk space information to the table:

CREATE PROC [CAPACITY_RECORD_DISK_SPACE]
AS
BEGIN


SET NOCOUNT ON

IF EXISTS (SELECT name FROM tempdb..sysobjects WHERE name = '##_DriveSpace')
DROP TABLE ##_DriveSpace

IF EXISTS (SELECT name FROM tempdb..sysobjects WHERE name = '##_DriveInfo')
DROP TABLE ##_DriveInfo


DECLARE @Result INT
, @objFSO INT
, @Drv INT
, @cDrive VARCHAR(13)
, @Size VARCHAR(50)
, @Free VARCHAR(50)
, @Label varchar(10)

CREATE TABLE ##_DriveSpace
(
DriveLetter CHAR(1) not null
, FreeSpace VARCHAR(10) not null

)

CREATE TABLE ##_DriveInfo
(
DriveLetter CHAR(1)
, TotalSpace bigint
, FreeSpace bigint
, Label varchar(10)
)

INSERT INTO ##_DriveSpace
EXEC master.dbo.xp_fixeddrives


-- Iterate through drive letters.
DECLARE curDriveLetters CURSOR
FOR SELECT driveletter FROM ##_DriveSpace

DECLARE @DriveLetter char(1)
OPEN curDriveLetters

FETCH NEXT FROM curDriveLetters INTO @DriveLetter
WHILE (@@fetch_status <> -1)
BEGIN
IF (@@fetch_status <> -2)
BEGIN

SET @cDrive = 'GetDrive("' + @DriveLetter + '")'

EXEC @Result = sp_OACreate 'Scripting.FileSystemObject', @objFSO OUTPUT

IF @Result = 0

EXEC @Result = sp_OAMethod @objFSO, @cDrive, @Drv OUTPUT

IF @Result = 0

EXEC @Result = sp_OAGetProperty @Drv,'TotalSize', @Size OUTPUT

IF @Result = 0

EXEC @Result = sp_OAGetProperty @Drv,'FreeSpace', @Free OUTPUT

IF @Result = 0

EXEC @Result = sp_OAGetProperty @Drv,'VolumeName', @Label OUTPUT

IF @Result <> 0

EXEC sp_OADestroy @Drv
EXEC sp_OADestroy @objFSO

SET @Size = (CONVERT(BIGINT,@Size) / 1048576 )

SET @Free = (CONVERT(BIGINT,@Free) / 1048576 )

INSERT INTO ##_DriveInfo
VALUES (@DriveLetter, @Size, @Free, @Label)

END
FETCH NEXT FROM curDriveLetters INTO @DriveLetter
END

CLOSE curDriveLetters
DEALLOCATE curDriveLetters


INSERT INTO Capacity_DiskSpaceTracking
(DriveLetter, Label, TotalSpace, FreeSpace)
SELECT DriveLetter, Label, TotalSpace, FreeSpace FROM ##_DriveInfo

/* Clean up. Drop the temp table */

DROP TABLE ##_DriveSpace
DROP TABLE ##_DriveInfo

END

3.) Create Job to Capture Disk Space Info every 12 hours and delete records older than 90 Days:

USE [msdb]
GO
/****** Object: Job [_DXDBA_Capacity_Disk_Space_Capture] Script Date: 09/29/2009 09:25:32 ******/

IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback
COMMIT TRANSACTION
GOTO EndSave
QuitWithRollback:
IF (@@TRANCOUNT > 0) ROLLBACK TRANSACTION
EndSave:



4.) Create a table to hold connection information:

USE [DXDBA]
GO
/****** Object: Table [dbo].[capacity_collection_info] Script Date: 09/29/2009 10:05:52 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[capacity_connection_info](
[db_name] [char](40) NULL,
[num_of_connx] [bigint] NULL,
[time_collected] [smalldatetime] NOT NULL CONSTRAINT [DF__capacity___time___300424B4] DEFAULT (getdate())
) ON [PRIMARY]

GO
SET ANSI_PADDING OFF

5.) Create a procedure to capture connection information:
IF it is SQL 2005:
create proc [_dxdba_capacity_user_connections]

as
begin

--create temp table
create table #users (
spid int,
ecid int,
status char( 40),
loginname char( 100),
hostname char( 100),
blk int,
dbname char( 40),
cmd varchar( 200),
request_id int
)

-- load the table
insert #users
exec sp_who

-- get the totals
insert into capacity_connection_info (db_name, num_of_connx)
(select dbname,
count(spid)
from #users
group by dbname)

drop table #users
end
IF it is SQL 2000:
create proc [_dxdba_capacity_user_connections]
as
begin

--create temp table
create table #users (
spid int,
ecid int,
status char( 40),
loginname char( 100),
hostname char( 100),

cmd varchar( 200))

-- load the table
insert #users

-- get the totals
insert into capacity_connection_info (db_name, num_of_connx)
(select dbname,
count(spid)

group by dbname)

drop table #users
end


6.) Create a Job to capture connection information every 3 hours and delete records older than 30 days:

17.) Before a report can be generated, each job must run at least twice. So you can wait 48 hours, or just manually trigger each job twice, then execute the following code to generate the report. Best formatting is achieved by executing in SSMS and specifying “results to text”:
