SQL Server資料庫日常檢查

1.1代碼檢查從昨天到現在，SQL代理Job有沒有運行失敗的，會把運行失敗的Job名字，步驟，運行時間，錯誤等級，錯誤原因羅列出來，方便查看，

----1.1  Check Job Fail List From Last Day To NowSELECT  j.[name],          h.step_id,          h.step_name,          h.run_date,          h.run_time,          h.sql_severity,          h.message,           h.server  FROM    msdb.dbo.sysjobhistory h          INNER JOIN msdb.dbo.sysjobs j              ON h.job_id = j.job_id          INNER JOIN msdb.dbo.sysjobsteps s              ON j.job_id = s.job_id                 AND h.step_id = s.step_id  WHERE    h.run_status = 0 -- Failure           AND h.run_date > CONVERT(int,CONVERT(varchar(10), DATEADD(DAY, -1, GETDATE()), 112))ORDER BY h.instance_id DESC;

1.2 檢查兩天內，運行時間超過30分鐘的Job，并按執行時間長短排序，時間2天和運行時間30分鐘，都是可以調整的，可以調整為自己需要的檢查范圍，代碼會把執行Job的名稱，運行時間，平均執行時間列出來，看是否有突然變化的運行情況，

----1.2  Check Jobs With Long Duration:30minutes(can modify to other value) From Last 2 Day To NowSELECT sj.name   , sja.start_execution_date,DATEDIFF (minute ,sja.start_execution_date,sja.stop_execution_date ) AS ExecutedMin,ja.AvgRuntimeOnSucceed/60 as AvgRuntimeOnSucceedMinFROM msdb.dbo.sysjobactivity AS sjaINNER JOIN msdb.dbo.sysjobs AS sj ON sja.job_id = sj.job_id INNERjoin(    SELECT job_id,    AVG    ((run_duration/10000 * 3600) + ((run_duration%10000)/100*60) + (run_duration%10000)%100)    +    NULLIF(0,STDEV    ((run_duration/10000 * 3600) + ((run_duration%10000)/100*60) + (run_duration%10000)%100)) AS 'AvgRuntimeOnSucceed'     FROM msdb.dbo.sysjobhistory    WHERE step_id = 0 AND run_status = 1    GROUP BY job_id) ja     ON sj.job_id = ja.job_idWHERE sja.start_execution_date IS NOT NULL --作業有開始   AND sja.stop_execution_date IS not NULL --作業結束   AND sja.start_execution_date>DATEADD(DAY,-2,GETDATE()) --作業2天內開始and DATEDIFF (minute ,sja.start_execution_date,sja.stop_execution_date )>30order by ExecutedMin desc

1.3 檢查資料庫錯誤日志，默認讀取的是當前log，篩選的是Error開頭的錯誤日志，可以根據需要篩選其他關鍵字，

----1.3  Check SQL Error LogDROP TABLE IF EXISTS #errorLog;  -- this is new syntax in SQL 2016 and later

CREATE TABLE #errorLog (LogDate DATETIME, ProcessInfo VARCHAR(64), [Text] VARCHAR(MAX));

INSERT INTO #errorLogEXEC sp_readerrorlog 

SELECT * FROM #errorLog aWHERE EXISTS (SELECT *               FROM #errorLog b              WHERE [Text] like 'Error:%'                AND a.LogDate = b.LogDate                AND a.ProcessInfo = b.ProcessInfo)

1.4 檢查含有資料庫檔案的磁盤的空間大小，可以看到剩余百分比，實際大小，使用大小等，

----1.4  Check HDD Free Spaceselect distinct convert(varchar(512), b.volume_mount_point) as [volume_mount_point], convert(varchar(512), b.logical_volume_name) as [logical_volume_name], convert(decimal(18,1), round(((convert(float, b.available_bytes) / convert(float, b.total_bytes)) * 100),1)) as [Drive_Free_Percent], convert(bigint, round(((b.available_bytes / 1024.0)/1024.0),0)) as [Drive_Free_MB], convert(bigint, round(((b.total_bytes / 1024.0)/1024.0),0)) as [Drive_Total_MB], convert(bigint, round((((b.total_bytes - b.available_bytes) / 1024.0)/1024.0),0)) as [Drive_Used_MB]from sys.master_files as [a]CROSS APPLY sys.dm_os_volume_stats(a.database_id, a.[file_id]) as [b]order by volume_mount_point  

1.5 檢查資料庫資料檔案和日志檔案的大小，默認排除了id為4以下的系統資料庫，可以根據需要調整，只觀察自己需要的資料庫，

----1.5  Check DB Data And Log Sizeselect distinct db_name(a.database_id) as [DatabaseName],database_id, a.name as [Logical_Name], convert(decimal(28,2), round(((a.size * 8.0) / 1024.00),2)) as [SizeMB] from sys.master_files as [a]where database_id>4order by  DatabaseName,Logical_Name
