I am trying to set up a SSIS Package where this sql query will run through all of my servers. (this part is done)I set that up to do a performance test on all the servers,however now I am trying to check disk space on all 128 servers as well. This query is not working for me though. I believe it is due to the temp. tables possibly? Can someone help me? Thanks,

Here's a simple script for getting volume capacity and free space info when you have mount points. It uses a combination of WMI, ADO, and VBSCript. You can trigger the script via a SQLAgent job or the Windows Task Scheduler. I have it running as a daily SQLAgent job. It populates a table that has date, host name, volume name, capacity, and free space columns. You'll need to modify this script to suit your particular environment and needs. I apologize that this is not a nice, clean SQL script, but I'm a sysadmin-turned-DBA and these are the tools I had available.Option Explicit'' *********** Modify the following constants to suit your environment ******************Const strRegPath = "HKLM\Software\scharfco\servers" 'REG_MULTI_SZ value containing names of servers to checkConst strConn = "Provider=SQLOLEDB;Data Source=MyServer;Trusted_Connection=Yes;Initial Catalog=MyDatabase"' ***************************************************************************************Const adOpenStatic = 3Const adLockOptimistic = 3Dim iDim strComputer, objWMIService, colItems, objItemDim WshShellDim objConnection, objCmddim strServer, strVolume, intCapacity, intFreeSpaceSet WshShell = Wscript.CreateObject("WScript.Shell")'Get server list from the Windows registry'you could also pull your server list from a tableDim strServerListstrServerList = WshShell.RegRead(strRegPath)Set objConnection = CreateObject("ADODB.Connection")set objCmd = CreateObject("ADODB.Command")objConnection.Open strConnobjCmd.activeConnection = objConnectionFor i = 0 To Ubound(strServerList) If isAlive(strServerList(i)) Then Set objWMIService = GetObject("winmgmts:\\" & strServerList(i) & "\root\cimv2") Set colItems = objWMIService.ExecQuery("Select * from Win32_Volume where DriveType = '3'") For Each objItem In colItems 'WScript.Echo strServerList(i) & "," & "," & objItem.Name & "," & int(objItem.Capacity / 1048576) & "," & int(objItem.FreeSpace / 1048576) strServer = strServerList(i) strVolume = objItem.Name intCapacity = int(objItem.Capacity / 1048576) intFreeSpace = int(objItem.FreeSpace / 1048576) wscript.echo strServer, strVolume, intCapacity, intFreeSpace objCmd.commandtext = "exec WriteVolumeStats @Server = '" & strServer & "', @VolumeID = '" & strVolume & "', @Capacity = " & intCapacity & ", @FreeSpace = " & intFreeSpace 'objCmd.execute Next End ifNextFunction IsAlive(strTarget)'Pings the target machine.

This is a very useful script. I have been looking for something like this. However, can you tell me how to use database mail rather than xp_sendmail since "this feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.. To send mail from SQL Server, use Database Mail." (SQL Server 2005 Books Online)

with WMI you have to be an admin on the server to use it.

RE: Monitoring Disk Space and Sending Alerts with TSQL

j.a.c — Fri, 14 Sep 2007 09:24:00 GMT

Hi Bob,

If you are using Windows 2003 you can use WMI to get the mountpoint information that you need. Check out the Win32_Volume Class:

http://msdn2.microsoft.com/en-us/library/aa394515.aspx

Also you can query any 2003 box remotely using this class.

I have a number of servers that I need to monitor, both SQL Server 2000 and 2005. I use similar code with an SSIS package to collect this information from all my servers to one database on one server. SQL Server magazine had some articles (http://www.sqlmag.com/Articles/ArticleID/95385/95385.html and http://www.sqlmag.com/Articles/ArticleID/95745/95745.html) that had information on how to set this up. Of course, you need a subscription to the magazine to read the articles.

RE: Monitoring Disk Space and Sending Alerts with TSQL

Bob Wright-325851 — Fri, 14 Sep 2007 07:57:00 GMT

There have been many articles on this subject and all them rely on xp_fixeddrives to report total and free disk space. This works well in smaller environments but in much larger environments, especially those including a SAN, this approach will fall short. Most larger organizations, ones which hire Sr. Level DBAs are moving towards Mount Points on the Windows Servers. The lack of drive letters, the need to spread multi-terabyte databases over dozens of filegroups, failover and DR environment integration, all facilitate the need for a different approach to space consideration and how to address the disk space.

WMI and many other tools in our SQL bag of tricks, fail to recoginize mountpoints in the environment. If you xp_fixeddrives or even a WMIC query to look a drive which has a mount point with a terabyte of dataspace, all that is returned in the available space on the local disks. This is really not going to help you and trust me, it looks "strange" on a report which you show 1.1 terabytes of data on a 17 Gb disk with 16 Gb Free.

There are ways to gather this information in C#, such as walking the directory tree, and adding the functionality through an extended stored procedure but then you have to roll that out to all the servers and in secure/large environment, that is not always an easy or well received task.

The other factor to consider is support for the developed solution. Writing C# is great for many add-ons but not all DBAs are comfortable with creating, maintaining and/or deploying C# applications or SQL stored procedures/functions.

The lack of this particular functionality (ability easily and accurately determine available/used disk space) and other similar functionaility is concerning and leaves many DBAs, who want to maintian a TSQL codebase, even if it uses COM XPs, at the mercy fo the monitoring software vendors out there. Since CHKDSK can return the correct information on drives which have Mount Points, which is what I currently use to gather space information for TSQL by parsing the output, then I feel Microsoft should have updated the xp_fixeddrives routine to report the correct information or at least provided and documented a way of gathering that information. Especiallys since SQL Server is by far the greatest benefactor of utilizing mount points to store the large amounts of data the want to boast the capability of being able to address.

This article and the use of the email system is well thought out and helpful but not as much in larger SQL farms which managing the data environment is even more critical. I would also suggest adding a table in your database to store sent alerts (emails) and build in the functionality of storing the messages as part of the routine. This will allow someone to do historical reporting and analysis of the alerts, this one and others, which have been sent out over a period of time without being dependent on reviewing the emails through a mail server and its client or through a mail interface.

bfraser — Fri, 14 Sep 2007 06:50:00 GMT

In our environment, we have RAID drives that allow unlimited growth. The only issue with that is that the DBA group doesn't set our databases to auto grow, so sometimes we hit the space limit set up for the particular database, even if we have plenty of disk space available.

Is there a way to write a stored proc to monitor & send an alert on the allocated disk space for a particular database?? That would be really useful for us.

Thanks!

OceanDeep — Fri, 14 Sep 2007 06:43:00 GMT

It is good to know more than one way to do that. My question is why this is better than using performance monitor and its alert to do the same thing. Isn't it lesser work or resources by using performance monitor to track disk space and send alert?

--The @runnum is a counter for each time you execute this script to keep track on history in the DISK_CAPP table

SET @Query ='INSERT Disk_Capp SELECT '''+@servername+''',*,cast(getdate() as varchar(20)),'+cast(@runnum as varchar(10))+' FROM OPENQUERY( [DBA_'+@servername+'],''SET FMTONLY OFF;EXEC master.dbo.sp_diskspace'')'exec ( @Query )

Mention that the you are authorized to use the SP_OAxxxxx procedures (open and close using the DBlinks 1 and 0 )

SET @Query_c1 ='declare @var1 varchar(3000) set @var1 = ''EXEC [DBA_'+@servername+'].master.dbo.sp_configure ''show advanced options'',1 go reconfigure go'' exec (@var1)'exec (@Query_c1)

SET @Query_c2 ='declare @var2 varchar(3000) set @var2 = ''EXEC [DBA_'+@servername+'].master.dbo.sp_configure ''Ole Automation Procedure'',1 go reconfigure go''exec (@var2)'exec (@Query_c2)

Previously it was giving error because i didn't have SQL Mail in Support Services.

Now it works fine for me. This is perfect.

Thanks
