Issue Of Blank Emails When Checking For Free Space On Disk Of Servers

Sep 22, 2006

Hello

I have got a script which checks the percentage of free space on the drivers of the servers and mails the DBA when it falls below a certain percentage , which can be set according to our requirements.

But I am getting blank emails even when , there is no issue of low free space.

Please help me out.

The code , 1st part of it is:

use master
go
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO
create PROCEDURE usp_diskspace
@Percentagefree int,
@error2 varchar(8000) OUTPUT
AS


SET NOCOUNT ON

CREATE TABLE #drives (id int identity(1,1),ServerName varchar(15),

CLOSE dcur
DEALLOCATE dcur
EXEC @hr=sp_OADestroy @fso

select @errortotalspace =convert(varchar(20),Totalsize), @errorfreespace =freespace, @free=CAST((FreeSpace/(TotalSize*1.0))*100.0 as int),@errordrive=Drive from #drives where id = @count

set @error2=@error2+@error+char(13)

end

end
set @count=@count+1
end

DROP TABLE #drives
set @date = convert(varchar(100), getdate(),109)

GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO


The 2nd step which sends the mail is :

set nocount on
declare @msg varchar(8000)
declare @minimumspace int
set @minimumspace = 10
set @msg = 'Running out of Hard Disk space on the Server: '+@@servername
exec usp_diskspace @minimumspace,@msg OUTPUT
print @msg
if @msg is not null


EXEC master.dbo.xp_smtp_sendmail
@FROM = N'fromaddress',
@TO = N'toaddress',
@server = N'smtp address',
@subject = N'Free Space of Drivers Test sqlserver2000!',
@type = N'text/html',
@message = @msg



How can I change to get the mail only when there is a free space issue.

Thanks

Checking For Free Disk Space And Getting Mail , When Falls Below A Certain Limit

Sep 13, 2006

Hello

I have a script which checks the disk space and when it falls a certain size , it mails the dba mail box.

I would like to know how I can change it , as a percentage calculation.

For example when the free space is less than 20% of the total space on the drive I should be receiving a mail.

The script I have is :

declare @MB_Free int

create table #FreeSpace(
Drive char(1),
MB_Free int)

insert into #FreeSpace exec xp_fixeddrives
-- Free Space on F drive Less than Threshold
if @MB_Free < 4096
exec master.dbo.xp_sendmail
@recipients ='dvaddi@domain.edu',
@subject ='SERVER X - Fresh Space Issue on D Drive',
@message = 'Free space on D Drive
has dropped below 2 gig'
drop table #freespace


Thanks

Checking Disk Space

May 14, 2008

Another question...

I need to check the space available on a specific disk (D on a remote server, again, this task will be executed from an SSIS package, if I have less than 60GB available, I have to delete some files.

How would you guys do this using VB.NET? If I had SQL Server installed on that box, I could achieve this executing a DOS command... But I don't...

Thanks!

Moving Tempdb To Free Up Disk Space

Nov 29, 2000

does anyone know if tempdb can be physically moved to a different partition on a disk drive on SQL Server 7.0? Since it can't be backed up I'm hesitant to use the sp_detach/sp_attach procedure because I don't want to crash it. If nothing else is available, I can attempt moving it this way at the end of the day and then just reboot to get tempdb back up again if the server fails, but I'd really appreciate a suggestion from someone who has more know-how than I do about system table operations. Thanks again

SQL 2K Unallocated Space Won't Free Up - HELP!

Nov 5, 2004

I've gone through the forum and have seen several others with a similar situation. I recently noticed my .mdf file grew to 200GB yet the data in the file is only about 40GB. I run sp_spaceused and get the following: database_size = 176GB, unallocated space = 134GB, reserved = 43GB, data = 17GB, index_size = 19GB, unused = 6GB.

I've tried "dbcc shrinkdatabase (mydb, truncateonly)", tried restarting server, tried running a maintenance plan including a reindex of the database, and I don't know what to do next.

Does anyone know how to free up this space?

Why Can't Get Available Free Space After Shrinking

Jul 3, 2015

My disk drive was full. So I deleted some records. Then I tried to shrink and it indicated available free space of around 5GB as indicated in the below image.

Once I ran the shrink for data file, though it completed successfully I didn't get the 5GB space as indicated. For log file shrink it shows available space of 200MB and when I run a log file shrink it does free up 200MB as indicated. So why is it not working with data file shrink? What am I doing wrong?

Database Consumes Available Free Space?

Jul 12, 2012

I inherited a SQL server (2005) that sits on a Windows 2003 box (upgrading to 2008 R2 and Win2008, ASAP) and on our SQL Data Drive (260GB - 22GB free) we have 16 databases (that are associated with our primary application). One database in particular is causing me quite a bit of pain - on Tuesdays. This table will consume all available free space (save 700kb) and place it within it's 'reserved' space. It's not being used and I can reclaim it by shrinking. I have done this for 3 consecutive weeks now and I have always thought that shrinking is not really a best practice.

Based on a job I scheduled to spit out various database stats I discovered the following:

Somewhere after 11pm on Monday (and on or before 11:30pm) the reserved space goes from 9GB down to 23 then 37MB on this particular database.

After 1:30am on Tuesday (and on or before 2:00am) the database consumes nearly all available disk space and thus expands its reserved space to 28GB

I believe it has something to do with the Indexes being rebuilt - per the Maintenance Plan the Index Rebuild is supposed to occur every Monday @ 11pm. On 6/18 it ran from 11pm - 11:44pm with no problems. Starting on 6/26 (and subsequently 7/2 and 7/9) they have started at 11 and ended anywhere between 2 - to 3 hours later. And with the following error:

Failed-1073548784) Executing the query "ALTER INDEX [PK_activityLog] ON [dbo].[activityLog] REBUILD WITH ( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, SORT_IN_TEMPDB = OFF, ONLINE = OFF ) " failed with the following error: "Could not allocate a new page for database 'FA_PROD_SDDS' because of insufficient disk space in filegroup 'PRIMARY'.

Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. The statement has been terminated.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

The database 'FA_PROD_SDSS' is the one that I am having issues with.

Extent Allocation/Free Space - SQL2000??

May 6, 2004

I've faced with this problem in my DB:

There are some tables that suffer inserts and deletes daily. These tables have 3 nonclustered indexes including the pk.

I perceived that the space used for these tables are growing day after day even ocurring daily deletes.

These inserts and deletes follow the keys of the pk in ascent order.

I ran DBCC SHOWCONTIG on the tables and got results like this:

- Avg. Bytes Free per Page.....................: 7996.3

When I transform the pk to clustered this problem doesn't happen.

You realized the consequence of this: the users complains because the DB is without space, but it's not true!

Anybody could help me to understand why the extents are not being deallocated?

Thank's for help!

Db Free Space And Login Timeout -strange

Feb 13, 2006

I saw something strange this morning that I can not work out in my head.

Customer contacted us saying that the login timeout for one of our web apps was timing out.

The login does a simple check of user name and password against a table and inserts the event into a tracking table. I traced the login routine and the query took zero seconds in the QA on the db server. Everything looked fine in the Task Manager and the Performance monitor except that the disk que spiked out when the login page was used. I pinged between the web and database server and that was fine. The disk had plenty of free space for the log and the mdf files. The db had about of 15mb of unallocated space. Nothing seemed to work until I allocated another 100 MB to the db on their test site. Suddenly no more time out. I tested the live site again and it was still happening (same db and web server). Bumped up the db size on the live site and boom no more problem.

The problem is "fixed" for the moment but I can not seem to reason why so I can actually fix the problem in the long run. I do not know why a simple little password routine would care about the difference between 15mb of unallocated space and 115 mb of unallocated space.

SQL 2012 :: Reclaiming Free Space In Database?

Having just archived quite a bit of data from the main Production DB, I now have around 15% free, reclaimable space sat in the data file.

I'm reluctant to run DBCC SHRINKFILE as that apparently causes a lot of Index fragmentation which will cause issues for performance - how else can the space be allocated back to the OS?

Log File Alert And Negative Free Space!?

Sep 24, 2007

We've got an alert setup on our production database to warn us when the log file(s) exceeds 7 gigs. The Alert is triggering:

"The SQL Server performance counter 'Log File(s) Size (KB)' (instance 'Lexus') of object 'SQLServer:Databases' is now above the threshold of 7000000.00 (the current value is 7057656.00)."

However, according to the file system, the database properties screen files, and properties tabs, the log files combined are at under 5 gigs so this alert should not be going off.

The scary part is, when going to right-click on the database, choosing "tasks" and going to "Shrink > Files", the "Free Space" shows negative numbers for the first log file:

Log 1
Currently Allocated space: 118.69 MB
Available Free Space: -5323.24 MB (-4485%)

Log 2
Currently Allocated space: 4853.13 MB
Available Free Space: 411.20 MB (7%)

Has anybody ever run into this? Should I be worried that there is a bigger issue at hand?

Thanks!
