free to monitor your sqlserver easy and safe and ...




Unlike AWR in Oracle, Sqlserver does not have offical way to make history performance information for checking. until today.

I made it. you can deploy it safe and easy.

Needless to day:


getCPU


CREATE PROCEDURE [dbo].[getCPU]

AS

BEGIN

DECLARE @ts_now bigint = (SELECT cpu_ticks/(cpu_ticks/ms_ticks)FROM sys.dm_os_sys_info);

SELECT TOP(500) SQLProcessUtilization AS [SQL Server Process CPU Utilization],

SystemIdle AS [System Idle Process],

100 - SystemIdle - SQLProcessUtilization AS [Other Process CPU Utilization],

DATEADD(ms, -6 * (@ts_now - [timestamp]), GETDATE()) AS [Event Time]

FROM (

SELECT record.value('(./Record/@id)[1]', 'int') AS record_id,

record.value('(./Record/SchedulerMonitorEvent/SystemHealth/SystemIdle)[1]', 'int')

AS [SystemIdle],

record.value('(./Record/SchedulerMonitorEvent/SystemHealth/ProcessUtilization)[1]',

'int')

AS [SQLProcessUtilization], [timestamp]

FROM (

SELECT [timestamp], CONVERT(xml, record) AS [record]

FROM sys.dm_os_ring_buffers

WHERE ring_buffer_type = N'RING_BUFFER_SCHEDULER_MONITOR'

AND record LIKE '%<SystemHealth>%') AS x

) AS y

ORDER BY record_id DESC;

END



getperformancetest


CREATE PROCEDURE [dbo].[getperformancetest]

AS

BEGIN

SELECT TOP 10

Left(SUBSTRING(qt.TEXT, (qs.statement_start_offset/2)+1

, ((CASE qs.statement_end_offset

WHEN -1 THEN DATALENGTH(qt.TEXT)

ELSE qs.statement_end_offset

END - qs.statement_start_offset)/2)+1), 200) AS "SQL_TEXT"

, qs.execution_count

, qs.total_worker_time /qs.execution_count/1000 as avg_worker_time

, qs.total_elapsed_time /qs.execution_count /1000 as avg_elapsed_time

, qs.total_physical_reads /qs.execution_count as avg_physical_reads

, qs.total_logical_reads /qs.execution_count as avg_logical_reads

, qp.query_plan

--, CAST(qp.query_plan AS nvarchar(max)) query_plan

FROM sys.dm_exec_query_stats qs

CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) qt

CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) qp

WHERE qs.last_execution_time > dateadd(minute, -1, getdate())

ORDER BY qs.total_elapsed_time/qs.execution_count DESC

END



checkcputest


create PROCEDURE [dbo].[checkcputest]

AS

BEGIN

DECLARE @SQL2 VARCHAR(MAX)

exec(@createtable)

set @inserttable='insert into cpu_'+@SQL2+' exec [dbo].[getCPU]'

exec(@inserttable)

END


checkperformancetest


create PROCEDURE [dbo].[checkperformancetest]

AS

BEGIN

DECLARE @SQL2 VARCHAR(MAX)

DECLARE @createtable VARCHAR(MAX)

DECLARE @inserttable VARCHAR(MAX)

DECLARE @inserttable2 VARCHAR(MAX)

DECLARE @@tablename2 VARCHAR(MAX)

exec(@createtable)

set @inserttable='insert into perf_'+@SQL2+' exec [dbo].[getperformancet

exec(@inserttable)

END



showdelperftable



CREATE PROCEDURE [dbo].[showdelperftable] @days int

AS

BEGIN

select 'drop table dbo.'+name from sys.tables where name like 'perf_%' and create_date < dateadd(day, @days, getdate())

order by name asc,create_date asc

END


checkoldtable2


CREATE PROCEDURE [dbo].[checkoldtable2] @days int

AS

BEGIN

declare @m int

declare @n int

declare @tmp nvarchar(MAX)

declare @droptableList TABLE (id int IDENTITY(1,1) NOT NULL,contents VARCHAR(35) NOT NULL)

SET NOCOUNT ON


INSERT @droptableList (contents) exec showdelperftable @days

set @m=(select count(*) from @droptableList)

set @n=1

while @n<=@m

begin

set @tmp=(select contents from @droptableList where id=@n)

exec (@tmp)

--print (@tmp+CHAR(5))

set @n=@n+1

end

end


checkperformance_every_6_minutes


exec checkperformancetest

go


checkoldtable2_daily_08:30


EXEC checkoldtable2 -7

go


checkcputest_daily_09:00


EXEC checkcputest

go


you can see final example
