Monitor Windows Server having SQL Services Agent Services Reporting Services

Hi guys! Yesterday my boss asked me to build a tool to monitor Windows servers and Sql server services. I searched on Google and find few codes, i modified the code changed powershell concept and made below code.

In this post I shall tell you about how you monitor your all servers. The only thing you need is SQL Server which runs with an account having admin privilege on the network, or you can monitor those systems, the account having admin rights.

Lets start-

Create a database and two tables-

----------------------------------------------------------------------

Use master
Go
Create Database DBAMonitor
GO
Use DBAMonitor
GO 

CREATE TABLE [dbo].[tbl_ServerInfo](
 [Id] [int] identity(1,1) Not NULL,
 [WindowsServerName] [varchar](100) Not NULL,
 [SQLinstanceName] [varchar](100)  NULL
) ON [PRIMARY]

CREATE TABLE [dbo].[tbl_ServiceInfo](
 [SQLServiceName] [varchar](500) NULL,
 [servicestatus] [varchar](100) NULL,
 [windowservername] [varchar](500) NULL,
 [startmode] [varchar](100) NULL,
 [UpdateDate] [datetime] NULL DEFAULT GETDATE(),
 [startname] [varchar](1000) NULL,
 [InstanceName] [varchar](1000) NULL,
 [ServerID] INT NULL
) ON [PRIMARY]

----------------------------------------------------------------------

Please add your server details on tbl_serverInfo you want to monitor-

----------------------------------------------------------------------

--For example

insert into [tbl_ServerInfo](windowsServerName,SQLinstanceName) values ('Proddb','Dashboard')
insert into [tbl_ServerInfo](windowsServerName,SQLinstanceName) values ('192.168.0.512','sql2008r2')
insert into [tbl_ServerInfo](windowsServerName,SQLinstanceName) values ('192.168.0.500','')
insert into [tbl_ServerInfo](windowsServerName,SQLinstanceName) values ('192.168.0.510','')

--Checking details

----------------------------------------------------------------------

Now we need to run below script, but make sure xp_cmdshell is enabled. To enable it, please run below code-

----------------------------------------------------------------------

sp_configure 'Show Advanced Options',1
go
reconfigure
go
sp_configure 'xp_cmdshell',1
go   
reconfigure
go

----------------------------------------------------------------------

Now run the script and look the power-

----------------------------------------------------------------------

For better results, Create a job and run the above script from sql agent.

You can also create mailer for same to notify.

The below code is to notify if any service is stopped or any server is down.

Drop And Recreate all indexes on all tables of a database :

How to use :

First execute both scripts (on SSMS) on your database and save the result. It will generate drop index  and create index for all tables on database.

After doing this, please execute drop indexes result and then execute create index result.

Please verify the result.

Recover Deleted data on Sql Server

Hi Today I will tell you how to recover the data in case data is deleted 
Please follow step by step & execute next step when first step will be finished.

Step 1 : Create a new fresh database and a table inside this database

USE master

GO

CREATE DATABASE TestDb
GO

USE TestDb
GO

CREATE TABLE TestTable (
 id INT identity(1, 1)
 ,NAME VARCHAR(50)
 ,Value INT
 ,ValueAt DATETIME DEFAULT(GetDate())
 )
GO

Step 2 : Create a Full Backup of this database

BACKUP DATABASE TestDb TO DISK = 'D:\TestDb_Full.bak'
WITH init
 ,format
 ,stats = 10
GO

Step 3 : Follow below DML On table dbo.TestTable

USE TestDb
GO

INSERT INTO TestTable ( NAME,Value)
SELECT 'Vimal' ,50
UNION
SELECT 'Kamal' ,250
UNION
SELECT 'Raj' ,1200
UNION
SELECT 'Swastika',150
UNION
SELECT 'Sibin' ,125
UNION
SELECT 'Manas' ,560
UNION
SELECT 'Amit' ,3200
GO

SELECT * FROM TestTable
GO

DELETE FROM TestTable WHERE id > 5
GO

SELECT * FROM TestTable
GO

 Step 4 : As data has been deleted. Now its time to recover that data.

Note : Here database is new & so as table. It is easy to recover. If you know the time of deleted data or approximate time you can recover data. But you will find it difficult if time range is too long or you forgot the time.
SELECT [Current LSN]
 ,[Transaction ID]
 ,[Operation]
 ,[Context]
 ,[AllocUnitName]
FROM fn_dblog(NULL, NULL)
WHERE [Operation] = 'LOP_DELETE_ROWS'
 AND [AllocUnitName] = 'dbo.TestTable'

SELECT [Current LSN]
 ,[Operation]
 ,[Transaction ID]
 ,[Begin Time]
 ,[Transaction Name]
 ,[Transaction SID]
 ,[AllocUnitName]
FROM fn_dblog(NULL, NULL)
WHERE [Transaction ID] = '0000:00000343'--<<Paste the TransactionID
 AND [Operation] = 'LOP_BEGIN_XACT'

--Copy CurrentLSN 00000021:000000b0:0001
SELECT CONVERT(INT, CONVERT(VARBINARY, '0x00000021', 1)) --Same Value
SELECT CONVERT(INT, CONVERT(VARBINARY, '0x000000b0', 1)) --Total 10 digit preceeded by 0
SELECT CONVERT(INT, CONVERT(VARBINARY, '0x0001', 1)) --Total 5 digit preceeded by 0

-->33000000017600001
SELECT Cast(CONVERT(INT, CONVERT(VARBINARY, '0x00000021', 1)) AS VARCHAR(5)) + RIGHT('0000000000' + CAST(CONVERT(INT, CONVERT(VARBINARY, '0x000000b0', 1)) AS NVARCHAR), 10) + RIGHT('00000' + CAST(CONVERT(INT, CONVERT(VARBINARY, '0x0001', 1)) AS NVARCHAR), 5) AS 'MarkPoint'
GO

Step 5 : Take a log backup now. For this recovery model of database should be Full or Bulk-logged(Right click on Database>>Properties>>Options>>Recovery Model)

BACKUP log TestDb TO DISK = 'D:\TestDb_log.trn'
GO

Step 6 : Restore Full backup of database
-- Starting first with restoring the FULL BACKUP with NORECOVERY
RESTORE filelistonly
FROM DISK = 'D:\TestDb_Full.bak';

RESTORE DATABASE [TestDb_New]
FROM DISK = 'D:\TestDb_Full.bak'
WITH MOVE 'TestDb' TO 'C:\TestDb.mdf'
 ,MOVE 'TestDb_log' TO 'C:\TestDb_log.ldf'
 ,REPLACE
 ,NORECOVERY;
GO

Step 7 : Restore log backup of database like below
RESTORE LOG TestDb_New
FROM DISK = 'D:\TestDb_log.trn'
WITH STOPBEFOREMARK = 'lsn:33000000017600001'
GO

Step 8 : Check the table data

USE TestDb_New
GO
SELECT * FROM dbo.TestTable

--Export the deleted rows from this table to original table

Step 9 : Drop tables

USE master
GO
DROP DATABASE TestDb
DROP DATABASE TestDb_New

-->The End<--

Note : Step 4 time range
SELECT [Current LSN]
 ,[Operation]
 ,[Transaction ID]
 ,[Begin Time]
 ,[Transaction Name]
 ,[Transaction SID]
 ,[AllocUnitName]
FROM fn_dblog(NULL, NULL)
WHERE --[Operation] = 'LOP_BEGIN_XACT'
 --and 
 [Begin Time] BETWEEN '2015/07/17 15:30:00:000'
  AND '2015/07/17 16:00:00:000'
