Hi,

I had received alert for Tempdb free sapce and reach the below threshold values.

I want to know.. Tempdb location and drive having enough free space available. Tempdb reached 200 MB it will be automatically extent & allocating sapce if database autogrowth enable. so we don't want take action if more free sapce available in Disk.

If it datafile size reached Full accoupied in disk and no free sapce available then we ill consider the take action.


DATE/TIME: 7/29/2013 11:11:47 AM

DESCRIPTION: The SQL Server performance counter 'Free Space in tempdb (KB)' (instance 'N/A') of object 'SQLServer:Transactions' is now below the threshold of 200.00 (the current value is 192.00).

Thanks
ananda

use the below script to find drive free space and DB free space.


use master

CREATE TABLE #TMPFIXEDDRIVES (
DRIVE CHAR(1),
MBFREE INT)

INSERT INTO #TMPFIXEDDRIVES
EXEC xp_FIXEDDRIVES

CREATE TABLE #TMPSPACEUSED (
DBNAME VARCHAR(50),
FILENME VARCHAR(50),
SPACEUSED FLOAT)

INSERT INTO #TMPSPACEUSED
EXEC( 'sp_msforeachdb''use ?; Select ''''?'''' DBName, Name FileNme, fileproperty(Name,''''SpaceUsed'''') SpaceUsed from sysfiles''')

SELECT C.DRIVE,
CASE
WHEN (C.MBFREE) > 1000 THEN CAST(CAST(((C.MBFREE) / 1024.0) AS DECIMAL(18,2)) AS VARCHAR(20)) + ' GB'
ELSE CAST(CAST((C.MBFREE) AS DECIMAL(18,2)) AS VARCHAR(20)) + ' MB'
END AS DISKSPACEFREE,
A.NAME AS DATABASENAME,
B.NAME AS FILENAME,
CASE B.TYPE
WHEN 0 THEN 'DATA'
ELSE TYPE_DESC
END AS FILETYPE,
CASE
WHEN (B.SIZE * 8 / 1024.0) > 1000 THEN CAST(CAST(((B.SIZE * 8 / 1024) / 1024.0) AS DECIMAL(18,2)) AS VARCHAR(20)) + ' GB'
ELSE CAST(CAST((B.SIZE * 8 / 1024.0) AS DECIMAL(18,2)) AS VARCHAR(20)) + ' MB'
END AS FILESIZE,
CAST((B.SIZE * 8 / 1024.0) - (D.SPACEUSED / 128.0) AS DECIMAL(15,2)) SPACEFREE,
B.PHYSICAL_NAME
FROM SYS.DATABASES A
JOIN SYS.MASTER_FILES B
ON A.DATABASE_ID = B.DATABASE_ID
JOIN #TMPFIXEDDRIVES C
ON LEFT(B.PHYSICAL_NAME,1) = C.DRIVE
JOIN #TMPSPACEUSED D
ON A.NAME = D.DBNAME
AND B.NAME = D.FILENME
and A.NAME = 'tempdb'
ORDER BY DATABASENAME asc

DROP TABLE #TMPFIXEDDRIVES

DROP TABLE #TMPSPACEUSED
