Implementace společného indikátoru výkonu MS SQL Server

Úvod

Často je potřeba vytvořit ukazatel výkonu, který by ukazoval aktivitu databáze související s předchozím obdobím nebo konkrétním dnem. V článku nazvaném „Implementace indikátoru výkonu SQL Server pro dotazy, uložené procedury a spouštěče“ jsme uvedli příklad implementace tohoto indikátoru.

V tomto článku popíšeme další jednoduchý způsob, jak sledovat, jak a jak dlouho trvá provádění dotazu, a také jak získat plány provádění pro každý časový bod.

Tato metoda je užitečná zejména v případech, kdy potřebujete generovat denní reporty, takže metodu můžete nejen automatizovat, ale také přidat do reportu s minimem technických detailů.

V tomto článku prozkoumáme příklad implementace tohoto běžného ukazatele výkonu, kde bude jako metrika sloužit celkový uplynulý čas.

Řešení

Nejprve poskytneme obecný algoritmus:

1) Pořiďte snímek aktivních dotazů
2) Uložte výsledek
3) Proveďte obecnou analýzu a výsledek uložte do tabulky na konci dne
4) Proveďte srovnávací analýzu přijatých dat

Nyní vám poskytneme některé podrobnosti.

Chcete-li pořídit snímek aktivních dotazů, vytvořte následující tabulky:

It is possible to automate the collection process. For example, if we add a call to this stored procedure with a schedule to the Agent task (for example, every 10 seconds) or by event (for example, [Databases]. [Active Transactions]. [_ Total]> 0).

At the end of the day, we perform a general analysis and save the result to the table calling the stored procedure.

 As you can see, the stored procedure also removes data from the [srv]. [RequestStatistics] table to prevent its expansion and ensure quick snapshots of active queries.
 
 We can create this stored procedure during daily Agent calls at the end of the day.
 
 Now, move to the very analysis of the collected data. To compare the current database state to the previous period, use the following view.
 
 Implementation of the view  
 USE [DATABASE_NAME]GOSET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOCREATE view [srv].[vIndicatorStatistics] asSELECT [DATE] ,[execution_count] ,[max_total_elapsed_timeSec] ,[max_total_elapsed_timeLastSec] ,[max_total_elapsed_timeLastSec]-[max_total_elapsed_timeSec] as [DiffSnapshot] ,([max_total_elapsed_timeLastSec]-[max_total_elapsed_timeSec])*100/[max_total_elapsed_timeSec] as [% Snapshot] , case when ([max_total_elapsed_timeLastSec]<[max_total_elapsed_timeSec]) then N'IMPROVED' else case when ([max_total_elapsed_timeLastSec]>[max_total_elapsed_timeSec]) then N'WORSENED' else N'IS NOT CHANGED' end end as 'IndicatorSnapshot' FROM [srv].[IndicatorStatistics]GO
 
 To compare the current database state to the specific day, execute the following query:
 with tbl1 as ( select min(total_elapsed_timeSec) as [MIN], max(total_elapsed_timeSec) as [MAX], avg(total_elapsed_timeSec) as [AVG], [sql_handle], count(*) as [Count], '2017-11-01' as [DATE] from [srv].[vRequestStatisticsArchive] where [start_time] between '2017-11-01T07:00:00' and '2017-11-01T21:00:00' group by [sql_handle]), tbl2 as ( select min(total_elapsed_timeSec) as [MIN], max(total_elapsed_timeSec) as [MAX], avg(total_elapsed_timeSec) as [AVG], [sql_handle], count(*) as [Count], '2017-11-08' as [DATE] from [srv].[vRequestStatistics] where [start_time] between '2017-11-08T07:00:00' and '2017-11-08T21:00:00' group by [sql_handle])select coalesce(tbl1.[sql_handle], tbl2.[sql_handle]) as [sql_handle], coalesce(tbl1.[MIN], 0) as [MIN 01.11.2017], coalesce(tbl2.[MIN], 0) as [MIN 08.11.2017], coalesce(tbl1.[MAX], 0) as [MAX 01.11.2017], coalesce(tbl2.[MAX], 0) as [MAX 08.11.2017], coalesce(tbl1.[AVG], 0) as [AVG 01.11.2017], coalesce(tbl2.[AVG], 0) as [AVG 08.11.2017], coalesce(tbl1.[Count], 0) as [Count 01.11.2017], coalesce(tbl2.[Count], 0) as [Count 08.11.2017]from tbl1left outer join tbl2 on tbl1.[sql_handle]=tbl2.[sql_handle];GO
 
 Here, we compare the performance from 07-00 to 21-00 on November 1 and 8, 2017 (for example, it is the working time of the enterprise to exclude the analysis of the routine tasks).
 
 We can generate this upload as a detailed report and attach it to the general report obtained from the [srv]. [VIndicatorStatistics] view.
 
 To understand how the query was executed and what happened from time to time, it’s enough to use the [srv]. [vRequestStatistics] view with the filter by [start_time] (the date and time of the request received).  
 Shrnutí
 
 In this article, we considered an example of implementing a general MS SQL Server performance indicator, which allows determining the database state related to the previous period or a specific day. As a metric, we used total elapsed time.
 
 This method is universal. It is necessary to configure it, up to your needs, as well as to determine the measure, such as what we will collect and compare.
 
 In addition, this approach allows detecting the issue immediately or for a certain period.
 
 With the received data, it is possible to create a robot that would make decisions what queries to improve or disable to prevent system bottlenecks and notifications of administrators.
