CloudWatch: org‑wide EC2
Amazon CloudWatch now supports organization‑wide enablement of detailed EC2 monitoring, making cross‑account metrics collection simpler for large AWS estates. That streamlines observability and troubleshooting across multi‑account setups for cloud teams managing dozens or hundreds of accounts. (x.com)
Amazon posted the CloudWatch org‑wide EC2 detailed‑monitoring enablement on Mar 16, 2026. (aws.amazon.com) Enablement rules in CloudWatch Ingestion (telemetry/enablement rules) can automatically turn on detailed monitoring for both existing and newly launched EC2 instances, enforce 1‑minute metric granularity, and be scoped to an entire AWS Organization, specific accounts, or resource tags. (aws.amazon.com) Creating an enablement rule triggers CloudWatch telemetry configuration that integrates with AWS Config by creating an internal service‑linked AWS Config recorder for the resource types defined in the rule. (docs.aws.amazon.com) AWS stated the auto‑enablement capability is available in all AWS commercial regions and that the resulting detailed EC2 metrics are billed according to Amazon CloudWatch pricing. (aws.amazon.com) CloudWatch detailed/custom metrics have historically been billed at about $0.30 per metric per month for the first 10,000 metrics and are prorated by the hour only when metrics are sent to CloudWatch. (docs.aws.amazon.com) For multi‑account estates running dozens or hundreds of accounts, the rule‑based model standardizes 1‑minute EC2 metrics collection across accounts and pairs with CloudWatch Metrics Insights, which supports querying up to two weeks of metric history for trend analysis.
