Hi,

It is possoble to monitor and alert the size of ndf file in databases in sql 2005? I can see you can do it in SQL 2008.

Thanks

Monitor when the size changes or when it's getting nearly full (so before it has to extend)?

Can the dmv sys.dm_db_file_space_usage give you the info you want? And integrate that in  a monitoring-report you already have.
http://msdn.microsoft.com/en-us/library/ms174412(v=sql.90).aspx

Or alerts
http://www.mssqltips.com/sqlservertip/1523/how-to-setup-sql-server-alerts-and-email-operator-notifications/
And look at the counters available if there is something that matches what you want.

Or you could use code like below in both SQL 2005/2008 (that takes into account the MAX file growth which SQL alert does not) and schedule a job to run the SP every how often you like and also you could change the treshold to whatever you want - below I used PercentFree < 25:



--data files
CREATE PROCEDURE dbo.dba_AlertDBDataSpace
AS
SET NOCOUNT ON;

create table #dbsize (DBFileName varchar(100), MAXSizeInMB decimal(12,4), UsedSpaceInMB  decimal(12,4), PercentFree decimal(12,4))
insert into #dbsize exec dbo.dba_CheckDBDataSpace
if exists (select * from #dbsize where PercentFree < 25)

begin
declare @report_file_name varchar(30),
            @sql varchar(max),
            @emailbody varchar(4000)
      
      set @sql = N'SET NOCOUNT ON
                        create table #dbsize (DBFileName varchar(100), MAXSizeInMB decimal(12,4), UsedSpaceInMB  decimal(12,4), PercentFree decimal(12,4))
                        insert into #dbsize exec dbo.dba_CheckDBDataSpace
                        select * from #dbsize where PercentFree < 25 order by 1,2;'

      SET @report_file_name = 'SQL_data_FileList.csv'
      SET @emailbody = 'WARNING !!! '+ CHAR(13) + CHAR(10)+'DB Files close to get FULL as at today(yyyy.mm.dd):  '+ convert(varchar(10),getdate(), 102)+ CHAR(13) + CHAR(10)

      EXEC msdb.dbo.sp_send_dbmail
            @profile_name = 'sqlmailProfile',
            @recipients='mail@mail.com',
            @subject = 'SQL ALERT - DB files almost FULL',
            @body = @emailbody,
            @body_format = 'TEXT',
            @query = @sql,
            @attach_query_result_as_file = 1,
            @execute_query_database = 'YourDBnameHere',
            @query_attachment_filename = @report_file_name,
            @query_result_header = 1,
            @query_result_separator = '      ',
            @query_result_no_padding = 1,
            @query_result_width = 1000;
end
GO
