Monitoring SQL Server Jobs: Script to Report Failed Jobs

Managing and monitoring SQL Server jobs is crucial for maintaining the health and performance of your SQL Server environment. One of the key aspects is to ensure that failed jobs are promptly reported and addressed. Below is a script that creates a report of failed SQL Server jobs and sends it via email. This script can be particularly useful for DBAs to automate the monitoring process.

Script Overview

The script performs the following tasks:

1. Create a Table: A temporary table Failed_Jobs is created to store details of the failed jobs.
2. Insert Data: Job failure details are inserted into the Failed_Jobs table. This includes jobs that failed in the last 24 hours.
3. Check for Failures: The script checks if there are any failed jobs.
4. Send Email: If there are any failures, an HTML-formatted email is sent, listing the details of the failed jobs.
5. Drop Table: The temporary table is dropped at the end of the script.

Here’s the complete script:

Automatic alert when cluster fail over happened

When  fail over happen, both SQL server and Agent service will get restarted, Then we will get Notification Alert When Fail Over Happened 

DECLARE @importance AS VARCHAR(6)

DECLARE @body AS NVARCHAR(1000)

SELECT  @InstanceName =@@SERVERNAME

SELECT  @NodeName = CAST(SERVERPROPERTY('ComputerNamePhysicalNetBIOS') AS NVARCHAR(200))

SELECT  @Subject  = 'Fail over Happened for Instance '+@InstanceName

SELECT  @body = 'Fail over Happened for Instance '+@InstanceName + '. This instance is currently running on the node '+@NodeName

SELECT  @importance ='High'

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:
