Using CloudWatch to Monitor EC2 :
Here’s an example of how AWS CloudWatch works with EC2 to monitor instance health:
-
Set up a CloudWatch Alarm:
- If you want to monitor the CPU utilization of an EC2 instance, you can create a CloudWatch alarm that triggers when CPU usage exceeds 80% for 5 minutes.
-
Create an Action for the Alarm:
- You could configure the alarm to automatically trigger an EC2 Auto Scaling action to add more instances to handle the increased load.
-
Visualization:
- You can visualize the CPU usage of your EC2 instances in a CloudWatch dashboard to identify trends and potential issues over time.
