Automating SQL Server Job Status Monitoring with Triggers

As a DBA, it's crucial to stay informed about changes in your SQL Server environment, especially when it comes to job status. Jobs being enabled or disabled can have significant impacts on operations, and timely alerts can help in taking necessary actions. Here, I’ll share a trigger script that automatically sends an email notification whenever a job is enabled or disabled in your SQL Server instance.

Script Overview

This trigger script is designed to:

  1. Monitor Job Status Changes: It detects when a job is enabled or disabled.
  2. Generate Alerts: It sends an email alert with details of the change, including the user who made the change, session ID, and host name.

Here's the complete trigger script:

Blocking alert from SQL Server

Below mentioned script will send the blocking queries which are blocked for more than 5 minutes and we need to create job for below script to run every 10 minutes
