SQL Server Alert: Trigger to Notify Job Enable/Disable Status Changes

As a SQL Server DBA, keeping track of job status changes is crucial, especially when jobs are disabled or enabled without prior notice. To enhance monitoring, I’ve created a SQL Server Trigger that automatically sends an email notification whenever a job's enabled/disabled status changes.

Here's the complete trigger script:

USE [msdb]

GO

CREATE TRIGGER [dbo].[JobStatusAlert]

   ON [dbo].[sysjobs]

   AFTER UPDATE

AS

BEGIN

    SET NOCOUNT ON;

    

    -- Check if job is enabled/disabled

    DECLARE @MailBody VARCHAR(300)

    

    -- Check if job status is changed (enabled/disabled)

    IF (SELECT TOP 1 CASE WHEN d.enabled = i.enabled THEN 0 ELSE 1 END

        FROM deleted d INNER JOIN inserted i

        ON d.job_id = i.job_id) = 1

    BEGIN

        -- Get session detail and create a message

        SELECT TOP 1 @MailBody = 'Job "'

            + i.name

            + '" is recently '

            + CASE WHEN i.enabled = 0 THEN ' DISABLED ' ELSE ' ENABLED ' END

            + ' by user '

            + login_name

            + ' with session id '

            + CAST(c.session_id AS VARCHAR(3))

            + ' and host name '

            + host_name + ' at '

            + CONVERT(VARCHAR(50), last_request_end_time, 109)

        FROM sys.dm_exec_connections c

        INNER JOIN sys.dm_exec_sessions s ON c.session_id = s.session_id

        CROSS APPLY sys.dm_exec_sql_text(most_recent_sql_handle)

        CROSS APPLY inserted i

        WHERE text LIKE '%exec msdb.dbo.sp_help_job%'

        AND text NOT LIKE '%SELECT c.session_id'

        ORDER BY last_read DESC;

        

        -- Send mail to DBA Team

        EXEC msdb.dbo.sp_send_dbmail

            @recipients='bajeyudu@SQLDBANOW.com', -- Change mail address accordingly

            @subject = 'Job Status Changed at SQLDBANOWDB01 Server',

            @profile_name = 'Sqlmail', -- Change profile name accordingly

            @body = @MailBody;

    END

END

GO
