CloudWatch monitoring service provides a simple way to begin collecting Amazon EBS metrics and status checks. The service can be accessed through the CloudWatch console, the AWS CLI, or via a third-party tool that integrates with the CloudWatch API. Additionally, an agent can be installed on EC2 instances to collect system-level information such as disk utilization metrics, providing more visibility into infrastructure components like EBS volumes. While CloudWatch provides general overview of volume fleet, it may not collect all EBS metrics, and custom metrics incur additional charges.
