Olá Pessoal,
Bom dia.
Hoje venho trazer pra vocês, a solução de algumas perguntas que eu me fazia nos ambientes em que trabalho, mas que eu não tinha como responder:
– Quem criou/alterou/excluiu um determinado job?
– Apaguei sem querer um Job.. Como faço pra recriá-lo rapidamente, sem precisar de restaurar backup ?
– Alguém desabilitou um determinado Job.. Quem foi ?
– Alguém alterou a descrição do Job.. Preciso identificar quem foi..
Para responder essas questões, iremos criar uma forma de monitorar a criação, modificação e exclusão de Jobs no SQL Server, através de uma trigger na tabela msdb.dbo.sysjobs.
Criando a tabela de histórico
Antes de criar a trigger que irá recuperar as informações, precisaremos criar a tabela que irá guardar as informações e criar o histórico.

CREATE TABLE [dbo].[Job_Audit] ( [Id_Auditoria] [INT] IDENTITY(1,1) PRIMARY KEY CLUSTERED NOT NULL, [Dt_Evento] [DATETIME] NULL DEFAULT (GETDATE()), [Ds_Usuario] [VARCHAR](50) NULL, [Ds_Job] [sysname] NULL, [Ds_Hostname] [VARCHAR](50) NULL, [Ds_Query] [VARCHAR](MAX) NULL, [Fl_Situacao] [TINYINT] NULL ) WITH (DATA_COMPRESSION=PAGE) |
Criação da trigger
Agora que criamos a tabela que terá as nossas informações, vamos criar a trigger que irá populá-la.

Consultando as informações
Agora que nossa trigger está ativada, faça algumas alterações em seus Jobs e veja como as informações são gravadas. É possível identificar a data/hora que o evento foi acionado, o usuário que realizou o evento e mesmo a query que foi executada no banco, seja para criação, exclusão ou alteração do Job.
Até mais!

Excelente me ajudou muito . Obrigado
Aqui não está gravando nada, devo alterar algo?
Perfeito. Ótimo Post. Vem muitas informacoes precisas.
