SYSTEMS +: SQL SERVER Monitoring Script

Problem

As a SQL Server DBA, dedicated to monitoring and administering many busy OLTP production environments, I always find myself trying to answer questions like:

What was SQL Server doing last night when the end users were experiencing slow application response times?
How much time the ABC job taken for execution?
Why the A job get failed?
Are the SQL services running?
What is the OLAP DB size?
Is the backup plan executed properly and what the size of the BKP files.

The answers to such questions are never easy to identify. So how can I figure this out?

Solution

The following script comes in handy because it captures the code the SQL Server engine is processing at any point in time and delivers it on email with following information.

Here is the query:

CREATE PROC ServerInfo

SET NOCOUNT ON

IF EXISTS(SELECT 1 FROM tempdb..sysobjects where name='##sqlservice')

DROP TABLE ##sqlservice

CREATE TABLE ##sqlservice (details VARCHAR(100))

IF EXISTS(SELECT 1 FROM tempdb..sysobjects where name='##agentservice')

DROP TABLE ##agentservice

CREATE TABLE ##agentservice (details VARCHAR(100))

WAITFOR DELAY '00:02'

DECLARE @sname VARCHAR(100), @starttime VARCHAR(30)

DECLARE @authmode VARCHAR(25), @subject VARCHAR(250)

DECLARE @insname VARCHAR(50),@agentname VARCHAR(50)

DECLARE @sqlstatus VARCHAR(100), @agentstatus VARCHAR(100)

DECLARE @dbstatus VARCHAR(100), @dbdetail VARCHAR(2000)

DECLARE @sctsql VARCHAR(200), @HTML VARCHAR(8000) ,@tableHTMLVARCHAR(8000)

DECLARE @dbcount int

select @dbcount=count (*) FROM sys.databases WHERE state_desc <>'ONLINE'

SELECT @sname = @@SERVERNAME

SELECT @authmode=case SERVERPROPERTY('IsIntegratedSecurityOnly') when 1then 'Windows' else 'Mixed' end

SELECT @starttime=CONVERT(VARCHAR(30),create_date,109) from sys.databaseswhere database_id=2

IF (serverproperty('InstanceName')) IS NOT NULL

BEGIN

SET@insname='mssql$'+CONVERT(VARCHAR(40),serverproperty('InstanceName'))

SET@agentname='sqlagent$'+CONVERT(VARCHAR(40),serverproperty('InstanceName'))

END

ELSE

BEGIN

SET @insname='mssqlserver'

SET @agentname='sqlserveragent'

END

SELECT @sctsql='EXEC master.dbo.xp_cmdshell ''sc query '+@insname+' | FIND "STATE"'''

INSERT ##sqlservice

EXEC (@sctsql)

SELECT @sctsql='EXEC master.dbo.xp_cmdshell ''sc query '+@agentname+' | FIND "STATE"'''

INSERT ##agentservice

EXEC (@sctsql)

IF EXISTS(SELECT 1 FROM ##sqlservice WHERE details LIKE'%RUNNING%')

SET @sqlstatus = 'Running'

ELSE

SET @sqlstatus = '<font color="red">Not Running</font>'

IF EXISTS(SELECT 1 FROM ##agentservice WHERE details LIKE'%RUNNING%')

SET @agentstatus = 'Running'

ELSE

SET @agentstatus = '<font color="red">Not Running</font>'

IF EXISTS (SELECT 1 FROM sys.databases WHEREstate_desc<>'ONLINE')

BEGIN
