DescribeFleetCapacity
This operation has been expanded to use with the Amazon GameLift containers feature, which is currently in public preview.
Retrieves the resource capacity settings for one or more fleets. For a container fleet, this operation also returns counts for replica container groups.
With multi-location fleets, this operation retrieves data for the fleet's home Region only. To retrieve capacity for remote locations, see DescribeFleetLocationCapacity.
This operation can be used in the following ways:
-
To get capacity data for one or more specific fleets, provide a list of fleet IDs or fleet ARNs.
-
To get capacity data for all fleets, do not provide a fleet identifier.
When requesting multiple fleets, use the pagination parameters to retrieve results as a set of sequential pages.
If successful, a FleetCapacity
object is returned for each requested
fleet ID. Each FleetCapacity
object includes a Location
property, which is set to the fleet's home Region. Capacity values are returned only for
fleets that currently exist.
Note
Some API operations may limit the number of fleet IDs that are allowed in one request. If a request exceeds this limit, the request fails and the error message includes the maximum allowed.

Request Parameters
For information about the parameters that are common to all actions, see Common Parameters.
The request accepts the following data in JSON format.
Note
In the following list, the required parameters are described first.
- FleetIds
-
A unique identifier for the fleet to retrieve capacity information for. You can use either the fleet ID or ARN value. Leave this parameter empty to retrieve capacity information for all fleets.
Type: Array of strings
Array Members: Minimum number of 1 item.
Pattern:
^fleet-\S+|^arn:.*:fleet\/fleet-\S+
Required: No
- Limit
-
The maximum number of results to return. Use this parameter with
NextToken
to get results as a set of sequential pages. This parameter is ignored when the request specifies one or a list of fleet IDs.Type: Integer
Valid Range: Minimum value of 1.
Required: No
- NextToken
-
A token that indicates the start of the next sequential page of results. Use the token that is returned with a previous call to this operation. To start at the beginning of the result set, do not specify a value. This parameter is ignored when the request specifies one or a list of fleet IDs.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 1024.
Required: No

Response Elements
If the action is successful, the service sends back an HTTP 200 response.
The following data is returned in JSON format by the service.
- FleetCapacity
-
A collection of objects that contains capacity information for each requested fleet ID. Capacity objects are returned only for fleets that currently exist. Changes in desired instance value can take up to 1 minute to be reflected.
Type: Array of FleetCapacity objects
- NextToken
-
A token that indicates where to resume retrieving results on the next call to this operation. If no token is returned, these results represent the end of the list.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 1024.
Errors

HTTP Status Code: 500
- InvalidRequestException
-
One or more parameter values in the request are invalid. Correct the invalid parameter values before retrying.
HTTP Status Code: 400
- NotFoundException

HTTP Status Code: 400
- UnauthorizedException
-
The client failed authentication. Clients should not retry such requests.
HTTP Status Code: 400
Examples
Request capacity status for a list of fleets
This example retrieves fleet capacity information for a list of two fleets. The first result shows capacity for a container fleet that's configured to hold five replica container groups per instance. The second result shows a fleet in the middle of a scale down event: instances are being terminated so that the active instances count matches the desired instances count.
HTTP requests are authenticated using an Amazon Signature Version 4 signature in the Authorization
header field.
