Cost dimensions allow you to slice and dice your cost information to provide insights on spend and potential savings. This page describes custom cost dimensions, but there are also RightScale-generated dimensions and bill-based dimensions.
Custom dimensions are dimensions that are specific to your organization. Today, only resource tag/label-based dimensions are supported.
Any resource tags (labels in Google) in your bill data can be enabled as custom dimensions. For Google and Microsoft Azure, all resource tags/labels are available in the bill data by default. For Amazon Web Services, resource tags must be configured as user-defined cost allocation tags in order for them to be available in the bill and be used as custom dimensions in Optima.
To configure a tag/label as a custom dimension, please email firstname.lastname@example.org with a list of the tags/labels that you would like configured. This will be user-controlled in the future.
