- To receive usage reports for AppStream 2.0, you can subscribe to them via the AppStream 2.0 console, AWS CLI or CreateUsageReportSubscription API operation. You need to enable usage reports separately for each AWS Region you want to receive data from. Usage reports are stored in an Amazon S3 bucket and there is no charge for subscribing, but standard Amazon S3 charges may apply. There are two types of reports: AppStream 2.0 Sessions Reports and AppStream 2.0 Applications Reports. Sessions reports are generated daily and include information about each user session. Applications reports are generated daily and include information about each application launch during a session. Reports are stored in a nested folder structure in your Amazon S3 account and can be analyzed using Amazon Athena.
