 This Guidance includes an option to send anonymized operational metrics to AWS. We use this data to better understand how customers use this Guidance and related services and products. When invoked, the following information is collected and sent to AWS: 
+  **Guidance ID** – The Guidance identifier 
+  **Unique ID (UUID)** – Randomly generated, unique identifier for each Data Transfer from Amazon Glacier Vaults to Amazon S3 deployment 
+  **Timestamp** – Data-collection timestamp 
+  **Data** – The Guidance collects and sends the following statistics: 
  +  **Region** – Selected AWS Region 
  +  **Version** – Version of the Guidance deployment 
  +  **StorageClass** – Selected destination S3 storage class 
  +  **RetrievalTier** – Type of Amazon Glacier retrieval (for example, Bulk) 
  +  **VaultSize** – Source Amazon Glacier vault size 
  +  **ArchiveCount** – Number of Amazon Glacier archives
