aws-cloudwatch

On July 31, 2026 AWS shipped CloudWatch managed Prometheus collectors. For the AWS Example 22 shape (100 hosts x 50 metrics @ 60s), OTLP ingestion is $54/mo vs $1,500 classic custom metrics if you do not double-ingest.

CloudWatch bills across ten distinct dimensions — Logs ingestion at $0.50/GB, Logs storage, custom metrics with cardinality multipliers, alarms tiered by resolution and type, dashboards at $3 each, Synthetics canary runs, RUM events, X-Ray traces, Container Insights, and cross-region replication. Logs ingestion is the largest line on most accounts.
