AWS Reserved Instance Coverage Report
The AWS Reserved Instance (RI) Coverage report helps you understand and monitor which of your AWS EC2 instances are covered by RIs. You can use it to identify the instances that are under-utilized as well as those that are running at on-demand rates, so you can adjust your RI purchases to optimize costs. If you have instances that are in frequent use and aren't covered by RIs, you may be able to save money by purchasing RIs for them.
You can select the currency for your report. All costs shown in the report will be converted to this currency.
To retrieve Reserved Instance Coverage information from Amazon, you must enable Amazon's Cost Explorer. For more information, see Set up your AWS account with Amazon Cost Explorer.
This report doesn't support any markup or discount cost adjustments you've made to the cost model and isn't available for Service Portal users.
This report shows only AWS EC2 reservations for Compute Instances.
There's a fee of $0.01 USD per request to AWS to retrieve recommendation data. Generally, two requests are required per report. For cloud accounts with many resources, multiple requests may be required. These request fees will be visible on the Cost Dashboard.

To see data points on the summary graph for a given month, if you intend to use Monthly Granularity, your date selection must include the last day of that month.
Granularity: Select Daily or Monthly depending on the level of detail you want to include in your report. To see data points on the summary graph for a given month, when you select Monthly, your Duration must include the last day of that month.
Cloud Account: You can select your AWS payer account, individual linked accounts, or a GovCloud account. When you select a payer account, you have the option to retrieve data for its linked accounts using the Linked Accounts setting described below. If you select a linked account that doesn't have direct access to Amazon's Cost Explorer, the associated payer account's access will be used. If you select a linked account, only data for that account will be shown in the report.
Region: The regions available will be the ones associated with the cloud account you selected. When you select a specific region, and are retrieving data for a payer account with the Include Linked Accounts option selected, then all accounts within that region are shown, even if they aren't managed by Commander. When you select All, with the Include Linked Accounts option selected, a superset of pre-configured regions is used. This superset includes selected regions for the payer account and all the linked accounts found in Commander.
Linked Accounts: You can select None to view data from only the cloud account you selected above. Select Include Linked Accounts to see data from the payer account and the linked accounts associated with the payer account, including any GovCloud accounts, even if the linked accounts aren't managed by Commander.
Currency: Select the currency for the report. All costs shown in the report will be converted to this currency.
