Assessing your storage activity and usage with Amazon S3 Storage Lens - Amazon Simple Storage Service

Assessing your storage activity and usage with Amazon S3 Storage Lens

Amazon S3 Storage Lens aggregates your usage and activity metrics and displays the information in the account snapshot on the Amazon S3 console home (Buckets) page, interactive dashboards, or through a metrics export that you can download in CSV or Parquet format. You can use the dashboard to visualize insights and trends, flag outliers, and receive recommendations for optimizing storage costs and applying data protection best practices. You can use S3 Storage Lens through the AWS Management Console, AWS CLI, AWS SDKs, or REST API.

How S3 Storage Lens works

Amazon S3 Storage Lens provides a single view of usage and activity across your Amazon S3 storage. It has drilldown options to generate insights at the organization, account, bucket, object, or even prefix level. It analyzes storage metrics to deliver contextual recommendations to help you optimize storage costs and apply best practices for protecting your data.

You can use S3 Storage Lens to generate summary insights, such as finding out how much storage you have across your entire organization, or which are the fastest growing buckets and prefixes. Identify outliers in your storage metrics, and then drill down to further investigate the source of the spike in usage or activity.

You can assess your storage based on S3 best practices, such as analyzing the percentage of your buckets that have encryption or S3 Object Lock enabled. And you can identify potential cost savings opportunities, for example, by analyzing your request activity per bucket to find buckets where objects could be transitioned to a lower-cost storage class.

Default dashboard

On the S3 console, S3 Storage Lens provides an interactive default dashboard that is updated daily. Metrics from this dashboard are also summarized in your account snapshot on the S3 console home (Buckets) page. You can create other dashboards and scope them by account (for AWS Organizations users), AWS Regions, and S3 buckets to provide usage metrics for free. For an additional charge, you can upgrade to receive advanced metrics and recommendations. These include usage metrics with prefix-level aggregation, activity metrics aggregated by bucket, and contextual recommendations (available only in the Amazon S3 console). For information about working with your S3 Storage Lens dashboard, see Using Amazon S3 Storage Lens on the console.

Metrics export

In addition to viewing the dashboard on the S3 console, you can export metrics in CSV or Parquet format to an S3 bucket of your choice for further analysis. For more information, see Viewing Amazon S3 Storage Lens metrics using a data export.
