Een gemeenschappelijke MS SQL Server-prestatie-indicator implementeren

Inleiding

Het is vaak nodig om een ​​prestatie-indicator te maken die database-activiteit met betrekking tot de vorige periode of specifieke dag laat zien. In het artikel getiteld "Implementatie van SQL Server-prestatie-indicator voor query's, opgeslagen procedures en triggers", hebben we een voorbeeld gegeven van het implementeren van deze indicator.

In dit artikel gaan we een andere eenvoudige manier beschrijven om bij te houden hoe en hoe lang de uitvoering van de query duurt, en ook hoe de uitvoeringsplannen voor elk tijdstip kunnen worden opgehaald.

Deze methode is vooral handig in gevallen waarin u dagelijkse rapporten moet genereren, zodat u de methode niet alleen kunt automatiseren, maar deze ook aan het rapport kunt toevoegen met minimale technische details.

In dit artikel zullen we een voorbeeld onderzoeken van het implementeren van deze algemene prestatie-indicator waarbij de totale verstreken tijd als maatstaf zal dienen.

Oplossing

Eerst bieden we een algemeen algoritme:

1) Maak een momentopname van actieve zoekopdrachten
2) Sla het resultaat op
3) Voer een algemene analyse uit en sla het resultaat aan het eind van de dag op in een tabel
4) Maak een vergelijkende analyse van de ontvangen gegevens

Nu gaan we wat details geven.

Maak de volgende tabellen om een ​​momentopname te maken van actieve zoekopdrachten:

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).  
 
Samenvatting
 

 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.
