    Custom SQL Alert - Multiple Numeric Return run against ONE server


      Hi! Hope this hasn't been answered though if so I couldn't find it...


      I have a custom SQL alert for disk space using this code (below), I want to be able to run it against only ONE of the servers that we monitor and send an alert to a specific group. I can't seem to get it to run only against one server...help?




      DECLARE @hr int, @fso int, @drive char(1), @odrive int, @TotalSize varchar(20);


      -- Create a temp table for our working data. Load free space info into it first for each drive

      IF OBJECT_ID('tempdb..#drives') IS NOT NULL

         DROP TABLE #drives

      CREATE TABLE #drives (drive char(1) PRIMARY KEY, FreeSpace int NULL,TotalSize int NULL)

      INSERT #drives(drive,FreeSpace) EXEC master.dbo.xp_fixeddrives


      -- Open up a connection to perfmon so we can get total space for a drive

      EXEC @hr=sp_OACreate 'Scripting.FileSystemObject',@fso OUT

      IF @hr <> 0 EXEC sp_OAGetErrorInfo @fso


      -- walk thru each drive and get the total space from perfmon

      DECLARE dcur CURSOR LOCAL FAST_FORWARD FOR SELECT drive from #drives ORDER by drive

      OPEN dcur FETCH NEXT FROM dcur INTO @drive



         EXEC @hr = sp_OAMethod @fso,'GetDrive', @odrive OUT, @drive

         IF @hr <> 0 EXEC sp_OAGetErrorInfo @fso EXEC @hr = sp_OAGetProperty @odrive,'TotalSize', @TotalSize OUT

         IF @hr <> 0 EXEC sp_OAGetErrorInfo @odrive

         UPDATE #drives SET TotalSize=CONVERT(numeric,@TotalSize)/1024/1024 WHERE drive=@drive

         FETCH NEXT FROM dcur INTO @drive


      -- cleanup after ourselves

      CLOSE dcur

      DEALLOCATE dcur

      EXEC @hr=sp_OADestroy @fso IF @hr <> 0 EXEC sp_OAGetErrorInfo @fso


      -- return the results to the Ignite alert

      -- For Ignite alerts, it expects this query to return the drive letter and then one more column

      -- If you want to alert on Free MB, leave the drive and FreeSpace columns uncommented

      -- If you want to alert on Free %, leave the drive and Free(%) columns uncommented - this is the default

      SELECT drive,

      --   TotalSize as 'Total(MB)',

      --   FreeSpace as 'Free(MB)',

         100.0 * FreeSpace / TotalSize 'Free(%)'

      FROM #drives

      where drive not LIKE '[tz]%'

      ORDER BY drive

      DROP TABLE #drives
