Amazon S3 Storage Lens groups aggregates metrics using custom filters based on object metadata. You can analyze and filter S3 Storage Lens metrics using prefixes, suffixes, object tags, object size, or object age. With Amazon S3 Storage Lens groups, you can also categorize your usage within and across Amazon S3 buckets. As a result, you'll be able to better understand and optimize your S3 storage.
To start visualizing the data for a Storage Lens group, you must first attach your Storage Lens group to an S3 Storage Lens dashboard. If you need to manage Storage Lens groups in the dashboard, you can edit the dashboard configuration. To check which Storage Lens groups are under your account, you can list them. To check which Storage Lens groups are attached to your dashboard, you can always check the Storage Lens groups tab in the dashboard. To review or update the scope of an existing Storage Lens group, you can view its details. You can also permanently delete a Storage Lens group.
To manage permissions, you can create and add user-defined AWS resource tags to your Storage Lens groups. You can use AWS resource tags to categorize resources according to department, line of business, or project. Doing so is useful when you have many resources of the same type. By applying tags, you can quickly identify a specific Storage Lens group based on the tags that you've assigned to it.
In addition, when you add an AWS resource tag to your Storage Lens group, you activate attribute-based access control (ABAC). ABAC is an authorization strategy that defines permissions based on attributes, in this case tags. You can also use conditions that specify resource tags in your IAM policies to control access to AWS resources.
