Menerapkan Indikator Kinerja MS SQL Server Umum

Pengantar

Seringkali ada kebutuhan untuk membuat indikator kinerja yang akan menunjukkan aktivitas database yang terkait dengan periode sebelumnya atau hari tertentu. Dalam artikel berjudul “Menerapkan Indikator Kinerja SQL Server untuk Kueri, Prosedur Tersimpan, dan Pemicu”, kami memberikan contoh penerapan indikator ini.

Dalam artikel ini, kami akan menjelaskan cara sederhana lainnya untuk melacak bagaimana dan berapa lama eksekusi kueri berlangsung, serta cara mengambil rencana eksekusi untuk setiap titik waktu.

Metode ini sangat berguna jika Anda perlu membuat laporan harian, sehingga Anda tidak hanya dapat mengotomatiskan metode ini tetapi juga menambahkannya ke laporan dengan detail teknis minimum.

Dalam artikel ini, kita akan mempelajari contoh penerapan indikator kinerja umum ini di mana Total Waktu yang Berlalu akan berfungsi sebagai metrik.

Solusi

Pertama, kami menyediakan algoritme umum:

1) Ambil snapshot dari query aktif
2) Simpan hasilnya
3) Lakukan analisis umum dan simpan hasilnya ke tabel di penghujung hari
4) Buat analisis komparatif dari data yang diterima

Sekarang, kami akan memberikan beberapa detail.

Untuk mengambil snapshot dari kueri aktif, buat tabel berikut:

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).  
 Ringkasan
 
 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.
