## Feature Feature **Generally available**: Two new features that provide better observability for Compute Engine reservations and deeper insights into their capacity usage and costs: * A new `consumedReservation` field in the VM instance details showing the full resource name of the consumed reservation, providing reservation consumption status on VMs and better visibility for resource management and troubleshooting. * Two new system labels in the BigQuery billing export for instances consuming a reservation and the unused portion of a reservation, providing more detailed cost analysis: * `compute.googleapis.com/reservation_name`: the short name of the Compute Engine reservation. * `compute.googleapis.com/reservation_project_id`: the Project ID owning the Compute Engine reservation. For more information, see the following: * [View consumption history for a given instance](https://cloud.google.com/billing/docs/how-to/bq-examples#view%5Fconsumption%5Ffor%5Fa%5Fgiven%5Finstance). * [Analyze usage distribution per project for a shared reservation](https://cloud.google.com/billing/docs/how-to/bq-examples#analyze%5Fusage%5Fdistribution%5Ffor%5Fa%5Fgiven%5Freservation). * [List all the instances consuming a reservation](https://cloud.google.com/billing/docs/how-to/bq-examples#list%5Fall%5Fthe%5Finstances%5Fconsuming%5Fa%5Freservation).
