Amazon CloudWatch added a feature allowing customers to define enablement rules to automatically activate detailed monitoring on existing and new EC2 instances within their AWS Organization. These rules can be scoped across all accounts, select accounts, or specific EC2 resources tagged by criteria, enabling standardized 1-minute metric collection universally or selectively.
This automation enhances observability by ensuring consistent, high-resolution metrics for Auto Scaling and resource utilization without manual setup per instance. Customers pay CloudWatch detailed monitoring rates, and this capability is available across all AWS commercial regions, aiding in operational efficiency and monitoring best practices.
