I want to be notified if I'm not getting the maximum discount from my Amazon EC2 Reserved Instances. How can I get a notification by email?

Resolution

To receive a notification when you're not getting the maximum discount from your Reserved Instances (RIs), use AWS Budgets.

Note: Before you begin, be sure that you have the necessary permissions to access Cost Explorer and AWS Budgets.

  1. Sign in to the Billing and Cost Management console, and then open the Budgets pane.
  2. Choose Create Budget.
  3. Select Reservation budget, and then choose Set your budget.
  4. For Reservation budget type, select RI Utilization. For all other options, choose what best fits your use case. For example, to be notified when your RI utilization drops below 90%, enter 90 for Notification criteria.
  5. Under Refine your budget, select all the options that fit your use case.
  6. For Email contacts, enter the email addresses where you want to receive a notification.
  7. Choose Confirm budget.
  8. Choose Create.

If you use these options, you're notified by email whenever you're receiving less than 90% of the potential discount that your Reserved Instances offer.

Note: Reserved Instance utilization data can take up to three days to update.
