Note

In the following list, the required parameters are described first.

AvailabilityZone

The name of the Availability Zone.

Type: String

Required: No

AvailableCapacity

The number of DB instances that remain available in this Availability Zone. Amazon RDS decreases this value when a DB instance takes a unit of reserved capacity in this Availability Zone, and it increases this value when a DB instance releases that unit.

A DB instance with a pending modification also holds a unit of reserved capacity. A DB instance has a pending modification when Amazon RDS accepts a change to the DB instance and applies that change later, during the maintenance window. Amazon RDS holds the unit from the time that it accepts the request. To find a DB instance with a pending modification, check PendingModifiedValues in the response of DescribeDBInstances.

Amazon RDS reports available capacity only for a reservation that is in the active state and not past its end date. Otherwise, this value is 0.

Type: Integer
