Fala galera!!!!!

Hoje quero demonstrar como implementei em um cliente da Vita Database Solutions uma coleta automatizada dos Wait Types ocorrendo em uma instância de banco de dados SQL Server.

Caso queira implementar em seu ambiente, basta utilizar o seguinte script:

USE [master]
go
CREATE TABLE WaitStats_Collection
(DateMonitored DATETIME2, Wait_Type VARCHAR(200),
Waiting_Tasks_Count INT,Percentage_WaitTime DECIMAL(9,2))
GO

CREATE PROCEDURE PR_COLLECT_WAITSTATS
AS
INSERT INTO WaitStats_Collection
SELECT
GETDATE() AS [DateMonitored],
wait_type AS Wait_Type,
waiting_tasks_count AS Waiting_Tasks_Count,
wait_time_ms * 100.0 / SUM(wait_time_ms) OVER() AS Percentage_WaitTime
FROM
sys.dm_os_wait_stats
WHERE
wait_type NOT IN

Espero que tenham gostado e não deixem de inscreverem-se no blog, no canal do youtube, no grupo de discussão SQLManiacs  e em nosso grupo no TELEGRAM.

Grande abraço.
