1. Choose the **Collection groups tab**. Your account's collection groups are displayed.

1.  Choose the **Name** of a collection group to display its details.

------
#### [ AWS CLI ]
+ Use the [list-collection-groups](https://docs.aws.amazon.com/cli/latest/reference/opensearchserverless/list-collection-groups.html) command to list all collection groups in your account.
