Viewing S3 Storage Lens metrics on the dashboards

In the Amazon S3 console, S3 Storage Lens provides an interactive default dashboard that you can use to visualize insights and trends in your data. You can also use this dashboard to flag outliers and receive recommendations for optimizing storage costs and applying data-protection best practices. Your dashboard has drill-down options to generate insights at the account, bucket, Amazon Web Services Region, prefix, or Storage Lens group level. If you've enabled S3 Storage Lens to work with Amazon Organizations, you can also generate insights at the organization level (such as data for all accounts that are part of your Amazon Organizations hierarchy). The dashboard always loads for the latest date that has metrics available.

The S3 Storage Lens default dashboard on the console is named default-account-dashboard. Amazon S3 pre-configures this dashboard to visualize the summarized insights and trends for your entire account and updates them daily in the S3 console. You can't modify the configuration scope of the default dashboard, but you can upgrade the metrics selection from the free metrics to the paid advanced metrics and recommendations. With advanced metrics and recommendations, you can access additional metrics and features. These features include advanced metric categories, prefix-level aggregation, contextual recommendations, and Amazon CloudWatch publishing.

You can disable the default dashboard, but you can't delete it. If you disable your default dashboard, it is no longer updated. You also will no longer receive any new daily metrics in S3 Storage Lens or in the Account snapshot section on the Buckets page. You can still see historic data in the default dashboard until the 14-day period for data queries expires. This period is 15 months if you've enabled advanced metrics and recommendations. To access this data, you can re-enable the default dashboard within the expiration period.

You can create additional S3 Storage Lens dashboards and scope them by Amazon Web Services Regions, S3 buckets, or accounts. You can also scope your dashboards by organization if you've enabled Storage Lens to work with Amazon Organizations. When you create or edit an S3 Storage Lens dashboard, you define your dashboard scope and metrics selection.

You can disable or delete any additional dashboards that you create.

  • If you disable a dashboard, it is no longer updated, and you will no longer receive any new daily metrics. You can still see historic data for free metrics until the 14-day expiration period. If you enabled advanced metrics and recommendations for that dashboard, this period is 15 months. To access this data, you can re-enable the dashboard within the expiration period.

  • If you delete your dashboard, you lose all your dashboard configuration settings. You will no longer receive any new daily metrics, and you also lose access to the historical data associated with that dashboard. If you want to access the historic data for a deleted dashboard, you must create another dashboard with the same name in the same home Region.

Viewing an Amazon S3 Storage Lens dashboard

The following procedure shows how to view an S3 Storage Lens dashboard in the S3 console. For use-case based walkthroughs that show how to use your dashboard to optimize costs, implement best practices, and improve the performance of applications that access your S3 buckets, see Amazon S3 Storage Lens metrics use cases.

Note

You can't use your account's root user credentials to view Amazon S3 Storage Lens dashboards. To access S3 Storage Lens dashboards, you must grant the required Amazon Identity and Access Management (IAM) permissions to a new or existing IAM user. Then, sign in with those user credentials to access S3 Storage Lens dashboards. For more information, see Amazon S3 Storage Lens permissions and Security best practices in IAM in the IAM User Guide.

  1. Sign in to the Amazon Web Services Management Console and open the Amazon S3 console at https://console.amazonaws.cn/s3/.

  2. In the left navigation pane, choose Storage Lens, Dashboards.

  3. In the Dashboards list, choose the dashboard that you want to view.

    Your dashboard opens in S3 Storage Lens. The Snapshot for date section shows the latest date that S3 Storage Lens has collected metrics for. Your dashboard always loads the latest date that has metrics available.

  4. (Optional) To change the date for your S3 Storage Lens dashboard, in the top-right date selector, choose a new date.

  5. (Optional) To apply temporary filters to further limit the scope of your dashboard data, do the following:

    1. Expand the Filters section.

    2. To filter by specific accounts, Amazon Web Services Regions, storage classes, buckets, prefixes, or Storage Lens groups, choose the options to filter by.

      Note

      The Prefixes filter and the Storage Lens groups filter can’t be applied at the same time.

    3. To update a filter, choose Apply.

    4. To remove a filter, click on the X next to the filter.

  6. In any section in your S3 Storage Lens dashboard, to see data for a specific metric, for Metric, choose the metric name.

  7. In any chart or visualization in your S3 Storage Lens dashboard, you can drill down into deeper levels of aggregation by using the Accounts, Amazon Web Services Regions, Storage classes, Buckets, Prefixes, or Storage Lens groups tabs. For an example, see Uncover cold Amazon S3 buckets.

Understanding your S3 Storage Lens dashboard

Your S3 Storage Lens dashboard has a primary Overview tab, and up to five additional tabs that represent each aggregation level:

  • Accounts

  • Amazon Web Services Regions

  • Storage classes

  • Buckets

  • Prefixes

  • Storage Lens groups

On the Overview tab, your dashboard data is aggregated into three different sections: Snapshot for date, Trends and distributions, and Top N overview.

For more information about your S3 Storage Lens dashboard, see the following sections.

Snapshot

The Snapshot for date section shows summary metrics that S3 Storage Lens has aggregated for the date selected. These summary metrics include the following metrics:

  • Total storage – The total amount of storage used in bytes.

  • Object count – The total number of objects in your Amazon Web Services account.

  • Average object size – The average object size.

  • Active buckets – The total number of active buckets in active usage with storage > 0 bytes in your account.

  • Accounts – The number of accounts whose storage is in scope. This value is 1 unless you are using Amazon Organizations and your S3 Storage Lens has trusted access with a valid service-linked role. For more information, see Using service-linked roles for Amazon S3 Storage Lens.

  • Buckets – The total number of buckets in your account.

Metric data

For each metric that appears in the snapshot, you can see the following data:

  • Metric name – The name of the metric.

  • Metric category – The category that the metric is organized into.

  • Total for date – The total count for the date selected.

  • % change – The percentage change from the last snapshot date.

  • 30-day trend – A trend-line showing the changes for the metric over a 30-day period.

  • Recommendation – A contextual recommendation based on the data that's provided in the snapshot. Recommendations are available with advanced metrics and recommendations. For more information, see Recommendations.

Metrics categories

You can optionally update your dashboard Snapshot for date section to display metrics for other categories. If you want to see snapshot data for additional metrics, you can choose from the following Metrics categories:

  • Cost optimization

  • Data protection

  • Activity (available with advanced metrics)

  • Access management

  • Performance

  • Events

The Snapshot for date section displays only a selection of metrics for each category. To see all metrics for a specific category, choose the metric in the Trends and distributions or Top N overview sections. For more information about metric categories, see Metrics categories. For a complete list of S3 Storage Lens metrics, see Amazon S3 Storage Lens metrics glossary.

The second section of the Overview tab is Trends and distributions. In the Trends and distributions section, you can choose two metrics to compare over a date range that you define. The Trends and distributions section shows the relationship between two metrics over time. This section displays charts that you can use to see the Storage class and Region distribution between the two trends that you are tracking. You can optionally drill down into a data point in one of the charts for deeper analysis.

For a walkthrough that uses the Trends and distributions section, see Identify buckets that don't use server-side encryption with Amazon KMS for default encryption (SSE-KMS).

Top N overview

The third section of the S3 Storage Lens dashboard is Top N overview (sorted in ascending or descending order). This section displays your selected metrics across the top number of accounts, Amazon Web Services Regions, buckets, prefixes, or Storage Lens groups. If you enabled S3 Storage Lens to work with Amazon Organizations, you can also see your selected metrics across your organization.

For a walkthrough that uses the Top N overview section, see Identify your largest S3 buckets.

Drill down and analyze by options

To provide a fluid experience for analysis, the S3 Storage Lens dashboard provides an action menu, which appears when you choose any chart value. To use this menu, choose any chart value to see the associated metrics values, and then choose from two options in the box that appears:

  • The Drill down action applies the selected value as a filter across all tabs of your dashboard. You can then drill down into that value for deeper analysis.

  • The Analyze by action takes you to the Dimension tab that you select and applies that tab value as a filter. These tabs include Accounts, Amazon Web Services Regions, Storage classes, Buckets, Prefixes (for dashboards that have Advanced metrics and Prefix aggregation enabled), and Storage Lens groups (for dashboards that have Advanced metrics and Storage Lens group aggregation enabled). With Analyze by, you can view the data in the context of the new dimension for deeper analysis.

The Drill down and Analyze by actions might be disabled if the outcome would yield illogical results or would not have any value. Both the Drill down and Analyze by actions apply filters on top of any existing filters across all tabs of the dashboard. You can also remove the filters as needed.

Tabs

The dimension-level tabs provide a detailed view of all values within a particular dimension. For example, the Amazon Web Services Regions tab shows metrics for all Amazon Web Services Regions, and the Buckets tab shows metrics for all buckets. Each dimension tab contains an identical layout consisting of four sections:

  • A trend chart that displays your top N items within the dimension over the last 30 days for the selected metric. By default, this chart displays the top 10 items, but you can decrease it to at least 3 items or increase it up to 50 items.

  • A histogram chart that shows a vertical bar chart for the selected date and metric. If you have a large number of items to display in this chart, you might need to scroll horizontally.

  • A bubble analysis chart that plots all items within the dimension. This chart represents the first metric on the x axis and the second metric on the y axis. The third metric is represented by the size of the bubble.

  • A metric grid view that contains each item in the dimension listed in rows. The columns represent each available metric, arranged in metrics category tabs for easier navigation.
