Topic 1 Question 471
A company receives an alert from an Amazon CloudWatch alarm. The alarm indicates that a web application that is running on Amazon EC2 instances is not responding to requests. The EC2 instances have a Red Hat Enterprise Linux operating system and are in an Auto Scaling group. The Auto Scaling group has a minimum capacity of 2 and a maximum capacity of 5.
An investigation reveals that the web application is experiencing out-of-memory errors. The company adds memory to the web application and wants to track operating system memory utilization. A CloudWatch memory metric does not currently exist for the EC2 instances in the Auto Scaling group.
What should a SysOps administrator do to provide a CloudWatch memory metric for the EC2 instances?
Use an Amazon Machine Image (AMI) that includes the CloudWatch agent.
Turn on CloudWatch detailed monitoring.
Turn on Instance Metadata Service Version 2 (IMDSv2).
Use an Amazon Machine Image (AMI) that is based on Amazon Linux.

A>>>>Amazon CloudWatch does not provide memory utilization metrics for EC2 instances by default. To enable memory utilization monitoring for EC2 instances, including those in an Auto Scaling group, the SysOps administrator must install the CloudWatch Agent and configure it to send memory metrics to CloudWatch.

By default, Amazon CloudWatch does not collect memory and disk space metrics from EC2 instances. To collect these additional metrics, you need to install the CloudWatch agent on your instances. Once installed and configured, the CloudWatch agent can collect system-level metrics such as memory utilization, which are not available by default in CloudWatch.
