Create CloudWatch Alarm to get SNS notification when CPU utilization goes higher than threshold.

Task 1: Launch an EC2 Linux instance and review its CPU utilization metrics once it gets running. Specially, review the Status check and Monitoring. When you go to the monitoring tab, you will see all the CloudWatch metrics. Task 2: Go to CloudWatch Management Console and View CPU utilization metrics on the dashboard. Moreover, you can find other metrics also here. Task 3: Create the Alarm for the EC2 instance by creating a static threshold CPU utilization. (Please remember minimum period should be 60 seconds and set the conditions properly so that the Alarm can get triggered). This is the condition where no load on the CPU of the EC2 instance. Task 4: Configure the actions of CloudWatch by creating a new topic and giving your email ID. Once you will create the SNS topic you will receive a confirmation E-Mail. Then click on the confirmation link and the services will be subscribed from your side. Task 5: Now view your SNS console and review all the available metrics here. Also, check your status on that subscription. It should be verified. (Your Email ID should be the Endpoint there) Task 6: The Main Agenda here is that when CPU utilization of the EC2 instance exceeds the threshold, an email notification should be sent to the given email address. Task 7: Finally, Save the created Alarm by reviewing all the metrics. Task 8: Check the proper working of the created alarm. Also set the different combinations of CPU utilization, threshold, and time to validate the CloudWatch service and SNS service functionality/working. Task 9: Install the Stress Testing Tool to increase the Load of CPU. Follow the steps given below to increase the CPU load of the EC2 instances using the Command Line. So, connect your EC2 Linux instance and perform a few steps on its terminal/command line interface. sudo dnf install stress stress --help stress --cpu 4 --timeout 180
