AWS Private CA began publishing utilization metrics such as the number of certificates issued per CA and the total number of CAs per Region to Amazon CloudWatch, enabling customers to track usage against service quotas. This visibility helps prevent disruptions by allowing proactive lifecycle and quota management.
Users can configure CloudWatch alarms to automate responses when thresholds approach, such as rotating certificates or provisioning new CAs. This monitoring is critical for maintaining availability of AWS services dependent on Private CA certificates and is supported across all Regions offering the service as of early 2026.
