Manage Linux subscriptions in License Manager
With AWS License Manager, you can view and manage commercial Linux subscriptions that your Amazon EC2 instances use. You can track utilization of your Linux subscriptions for the AWS Regions and accounts in AWS Organizations that you've defined in your settings. License Manager gives you a comprehensive view of your running instances that use Linux subscriptions. It also indicates when an instance has more than one subscription defined.
The data that License Manager discovers is aggregated and displayed in the License Manager console and in the Amazon CloudWatch dashboard. You can also access your subscription data through the AWS CLI and the License Manager Linux subscription API or associated SDKs.
Linux license subscriptions can come from the following sources:
Subscription-included AMIs
-
Red Hat Enterprise Linux (RHEL)
-
RHEL Bring Your Own Subscription model (BYOS) with the Red Hat Cloud Access Program
-
SUSE Linux Enterprise Server
-
Ubuntu Pro subscription-included AMI
Third-party subscription providers
-
RHEL subscription from Red Hat Subscription Manager (RHSM)
Linux subscription discovery uses the eventual consistency model. A consistency model determines the manner and timing in which data is loaded and presented in your Linux subscriptions view. With this model, License Manager ensures that your Linux subscription data is updated periodically from your resources. In the event that some data is not ingested during these intervals, the information is delivered at the next metric emission. This behavior can delay resources, such as newly launched EC2 commercial Linux instances, from displaying in the Linux subscriptions dashboard.
Note
It can take up to 36 hours for the initial resource discovery to complete, and up to 12 hours for newly launched instances to be discovered and reported. Once your resources are discovered, Amazon CloudWatch metrics are emitted hourly for Linux subscriptions data.
If your accounts are in AWS Organizations, you can register a member account as the delegated administrator. For more information, see Delegated administrators.
Duplicate subscriptions detected
When License Manager detects two Linux subscriptions on the same EC2 instance, it sets the duplicate subscription alert. You can view and filter Linux subscription data from the Instances page in the License Manager console.
Red Hat Enterprise Linux 7 Extended Lifecycle Support (RHEL 7 ELS) instances: When you launch an instance from a subscription-included AMI for RHEL 7 ELS, you should still register your instance with Red Hat and consume an entitlement. In this case, License Manager reports a duplicate subscription, but that's the expected behavior.
Other Red Hat Linux instances: We recommend that
you search the subscription inventory in the Red Hat
Hybrid Cloud Console
