Certificate storage audit logs

AWS CloudHSM writes audit logs for certificate storage operations that modify data to a separate Amazon CloudWatch Events log stream within your cluster's CloudWatch log group. This log stream is named for the cluster, not for a specific HSM within the cluster.

For information about accessing audit logs in CloudWatch, see Working with Amazon CloudWatch Logs and AWS CloudHSM Audit Logs.
