FOCUS column
CapacityReservationId
The identifier of the capacity reservation the charge relates to. A capacity reservation holds capacity in a region or zone whether or not it is used, and is distinct from a commitment discount: it guarantees availability rather than a price. Charges for unused reserved capacity carry this id with no running resource.
Example
A row for reserved but idle capacity carries the reservation’s id here and a CapacityReservationStatus of “Unused”.
Where it comes from, per export
The export column that feeds CapacityReservationId in each format the platform ingests, and the transform applied. A format with no row does not carry the column; the value is then absent rather than guessed.
| Export | Source column | Transform |
|---|---|---|
| AWS Data Exports, FOCUS | CapacityReservationId | as is |
| Azure Cost Management, FOCUS export | CapacityReservationId | as is |
| Azure Cost Details (actual cost) | Not carried | — |
| Azure Cost Details (amortized cost) | Not carried | — |
| Google Cloud detailed billing export | Not carried | — |
How Runcost uses it
Runcost attributes reserved-capacity charges to the owner who reserved them, and reports the unused share so it is a decision rather than a leak.
