Amazon S3 Storage Lens metrics glossary
The Amazon S3 Storage Lens metrics glossary provides a complete list of free and advanced metrics for S3 Storage Lens.
S3 Storage Lens offers free metrics for all dashboards and configurations, with the option to upgrade to advanced metrics.
-
Free metrics contain metrics that are relevant to your storage usage, such as the number of buckets and the objects in your account. Free metrics also include use-case based metrics, such as cost-optimization and data-protection metrics. All free metrics are collected daily, and data is available for queries for up to 14 days.
-
Advanced metrics include all the metrics in free metrics along with additional metrics, such as advanced performance, advanced data protection, and advanced cost optimization metrics. Advanced metrics also include additional metric categories, such as activity metrics and detailed status-code metrics. Advanced metrics data is available for queries for 15 months.
There are additional charges when you use S3 Storage Lens with advanced metrics and recommendations. For more information, see Amazon S3 pricing
. For more information about advanced metrics and recommendations features, see Metrics selection. Note
For Storage Lens groups, only free tier storage metrics are available. Advanced tier metrics are not available at the Storage Lens group level.
Metric names
The Metric name column in the following table provides the name of each S3 Storage Lens in the S3 console. The CloudWatch and export column provides the name of each metric in Amazon CloudWatch and the metrics export file that you can configure in your S3 Storage Lens dashboard.
Derived metric formulas
Derived metrics are not available for the metrics export and the CloudWatch publishing option. However, you can use the metrics formulas shown in the Derived metrics formula column to compute them.
Interpreting the Amazon S3 Storage Lens prefix symbols for metrics unit multiples (K, M, G, and so on)
S3 Storage Lens metrics unit multiples are written with prefix symbols. These prefix symbols
match the International System of Units (SI) symbols that are standardized by the
International Bureau of Weights and Measures (BIPM). These symbols are also used in the
Unified Code for Units of Measure (UCUM). For more information, see List of SI prefix
symbols
Note
-
The unit of measurement for S3 storage bytes is in binary gigabytes (GB), where 1 GB is 230 bytes, 1 TB is 240 bytes, and 1 PB is 250 bytes. This unit of measurement is also known as a gibibyte (GiB), as defined by the International Electrotechnical Commission (IEC).
-
When an object reaches the end of its lifetime based on its lifecycle configuration, Amazon S3 queues the object for removal and removes it asynchronously. Therefore, there might be a delay between the expiration date and the date when Amazon S3 removes an object. S3 Storage Lens doesn't include metrics for objects that have expired but haven't been removed. For more information about expiration actions in S3 Lifecycle, see Expiring objects.
-
Amazon S3 stores metadata (object key, timestamps, etc.) for every object, which requires minimum storage even for 0KB data files. This is why 0KB objects appear in the (0KB-128KB] size range in S3 Storage Lens.
-
S3 Storage Lens provides best-effort tracking of cross-region data transfers, primarily focusing on requests from customer-managed resources like EC2 instances. Requests made through AWS PrivateLink or certain in-Region requests are unclassified.
The following table shows the S3 Storage Lens metrics glossary.
