I tried to track Amazon EC2 termination event

2022.07.30

Overview

In this article, we used Cloudwatch Events to send instance state change notification events to SNS Topic.
Here we have created a CloundWatch Events rule that will send an event to an SNS Topic
when an Amazon EC2 instance gets Terminated.
Resources to create:

SNS Topic CloudWatch Events EC2 Instance

I tried

  • Let's, Create an EC2 instance
    • This time I am creating an EC2 Instance with Basic Configuration

  • Create an SNS Topic with an email address you have access to

    • After Creating a Subscription it is needed to Confirm the Email you Can go to your inbox you will find AWS Notification
    • click the link and you will successful message

  •  Create CloudWatch Event Rules
    • Open CloudWatch> Events>Rule

  1. Create Rules

Fill in the detail as shown in Screen Shot below

Select the SNS topic we Created Before

Your Event pattern Preview should look like this
