# Attaching or removing S3 Storage Lens groups to or from your dashboard
<a name="storage-lens-groups-dashboard-console"></a>

After you've upgraded to the advanced tier in Amazon S3 Storage Lens, you can attach a [Storage Lens group](https://docs.amazonaws.cn/AmazonS3/latest/userguide/storage-lens-groups-overview.html) to your dashboard. If you have several Storage Lens groups, you can include or exclude the groups that you want. 

Your Storage Lens groups must reside within the designated home Region in the dashboard account. After you attach a Storage Lens group to your dashboard, you'll receive the additional Storage Lens group aggregation data in your metrics export within 48 hours.

**Note**  
If you want to view aggregated metrics for your Storage Lens group, you must attach it to your Storage Lens dashboard. For examples of Storage Lens group JSON configuration files, see [S3 Storage Lens example configuration with Storage Lens groups in JSON](S3LensHelperFilesCLI.md#StorageLensGroupsHelperFilesCLI). 

## Using the S3 console
<a name="storage-lens-groups-attach-dashboard-console"></a>

**To attach a Storage Lens group to a Storage Lens dashboard**

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

1. In the left navigation pane, under **Storage Lens**, choose **Dashboards**.

1. Choose the option button for the Storage Lens dashboard that you want to attach a Storage Lens group to.

1. Choose **Edit**.

1. Under **Metrics selection**, choose **Advanced metrics and recommendations**.

1. Select **Storage Lens group aggregation**.
**Note**  
By default, **Advanced metrics** is also selected. However, you can also deselect this setting as it's not required to aggregate Storage Lens groups data.

1. Scroll down to **Storage Lens group aggregation** and specify the Storage Lens group or groups that you either want to include or exclude in the data aggregation. You can use the following filtering options:
   + If you want to include certain Storage Lens groups, choose **Include Storage Lens groups**. Under **Storage Lens groups to include**, select your Storage Lens groups.
   + If you want to include all Storage Lens groups, select **Include all Storage Lens groups in home Region in this account**.
   + If you want to exclude certain Storage Lens groups, choose **Exclude Storage Lens groups**. Under **Storage Lens groups to exclude**, select the Storage Lens groups that you want to exclude.

1. Choose **Save changes**. If you've configured your Storage Lens groups correctly, you will see the additional Storage Lens group aggregation data in your dashboard within 48 hours.

**To remove a Storage Lens group from an S3 Storage Lens dashboard**

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

1. In the left navigation pane, under **Storage Lens**, choose **Dashboards**.

1. Choose the option button for the Storage Lens dashboard that you want to remove a Storage Lens group from.

1. Choose **View dashboard configuration**.

1. Choose **Edit**.

1. Scroll down to the **Metrics selection** section.

1. Under **Storage Lens group aggregation**, choose the **X** next to the Storage Lens group that you want to remove. This removes your Storage Lens group.

   If you included all of your Storage Lens groups in your dashboard, clear the check box next to **Include all Storage Lens groups in home Region in this account**. 

1. Choose **Save changes**.
**Note**  
It will take up to 48 hours for your dashboard to reflect the configuration updates.
