Your engineer is concerned about high CPU utilization on several of your EC2 instances. What service should you use to monitor this?

• Service Catalog
• CloudWatch
• Trusted Advisor
• Config

CloudWatch is the primary monitoring tool in AWS.

Amazon CloudWatch monitors your Amazon Web Services (AWS) resources and the applications you run on AWS in real time. You can use CloudWatch to collect and track metrics, which are variables you can measure for your resources and applications.

This frees up important resources and allows you to focus on building applications and business value.
