Tag-Based Cost Reporting


Tags are key-value pairs associated with cloud resources on a cloud provider. The key is mandatory and value is optional. Tags can be user-defined or system-defined. Similar to billing units, tags are also used for cost breakdown at a deeper granular level. The tags are discovered through the Tag Sync background process. See Data Collection.

Use the Tag-Based Cost report to enable cost reporting for tags in the associated cloud accounts. Tag-based cost reporting is disabled by default. By enabling this feature and by enabling the tags, you may incur an expense on your billing account (for example, on AWS the expenses are recorded as Cost Explorer expenses).

Sharing of tag-based cost groups is supported in Cost Optimizer 5.1.2 and later releases. When tag-based cost reports are shared, the sharing results in displaying additional cost, inventory, and recommendations for the resources associated with the cost groups.

Enable Cost Reporting

Tag-based cost reporting is available for AWS and Azure clouds only. The tags are automatically fetched from the cloud providers by the Tag Sync background process that runs every day at 01:00 hours GMT. As mentioned, tag-based cost reporting is disabled, you enable tag-based cost reporting by setting the toggle On the button at the top of the page. Invoice collection is triggered 30 minutes after you have toggled On the button. You would also notice that all Azure tags are OFF by default, whereas few AWS tags are enabled by default. The AWS tags that are On by default are the incurring costs tags. To enable tag-based cost reporting for Azure tags, you must set the toggle to ON in the Cost Reporting column against the tag for which you want to display the cost. Additionally, you can set the toggle to ON for AWS tags, as appropriate.

Tags that are enabled (toggle set to ON) only will be listed in the Unassigned Tags list for association with a cost group. See How Do I... > Associate a Tag for additional context.
