Analyze System and Guest Level Metrics for Amazon EC2 Instances and On-Premise Servers

Answer - A.

This is mentioned in the AWS Documentation.

The unified CloudWatch agent enables you to do the following.

Collect more system-level metrics from Amazon EC2 instances, including in-guest metrics, in addition to the metrics listed in Amazon EC2 Metrics and Dimensions.

The additional metrics are listed in Metrics Collected by the CloudWatch Agent.

Collect system-level metrics from on-premises servers.

These can include servers in a hybrid environment as well as servers not managed by AWS.

Collect logs from Amazon EC2 instances and on-premises servers, running either Linux or Windows Server.

Option B is incorrect since this is used for API monitoring.

Option C is incorrect since this is used for monitoring configuration changes.

Option D is incorrect since monitoring can also be configured for on-premise servers.

The correct answer is A. Ensure the Cloudwatch agent is present on the servers.

Explanation:

Amazon CloudWatch is a monitoring and management service that provides data and actionable insights for resources like Amazon EC2 instances, Amazon RDS databases, and more. CloudWatch can collect data, gain insights, and alert you to keep your applications running smoothly.

To monitor system-level metrics, you need to install and configure the CloudWatch agent on the Amazon EC2 instances and on-premise servers. The CloudWatch agent allows you to collect both system-level metrics such as CPU utilization, disk usage, and memory usage, as well as custom metrics that you define.

Option B, creating a trail in CloudTrail, would not help in analyzing system-level and guest-level metrics. CloudTrail is primarily used to record API calls made in your AWS account, such as creating an EC2 instance or modifying a security group.

Option C, enabling AWS Config, would also not help in analyzing system-level and guest-level metrics. AWS Config is a service that enables you to assess, audit, and evaluate the configuration of your AWS resources.

Option D, moving on-premise servers to AWS, is not a prerequisite for monitoring system-level metrics. CloudWatch can collect data from both Amazon EC2 instances and on-premise servers, provided that the CloudWatch agent is installed and configured on them.

Therefore, the correct answer is A. Ensure the Cloudwatch agent is present on the servers.
