As of Release 2.17.0, we added the ability to drill down on resource-level spend for a month using tag keys/names and tag values, giving you greater visibility into your OU and project spend for specific tags. In order to use these tags (called cost allocation tags), they must first be turned on in the Billing and Cost Management console within AWS.
To learn how to turn on cost allocation tags, see the Activating User-Defined Cost Allocation Tags documentation from AWS. Once they are turned on your selected tags and values will automatically appear as options within cloudtamer.io reporting drop-down menus.
If you're using both AWS and Azure, you can take advantage of cloudtamer.io's unified tagging by using the same tags within both platforms. Read more about unified tagging in the Report Builder article.
