getReservationUtilization method

Future<GetReservationUtilizationResponse> getReservationUtilization({
  1. required DateInterval timePeriod,
  2. Expression? filter,
  3. Granularity? granularity,
  4. List<GroupDefinition>? groupBy,
  5. String? nextPageToken,
})

Retrieves the reservation utilization for your account. Management account in an organization have access to member accounts. You can filter data by dimensions in a time period. You can use GetDimensionValues to determine the possible dimension values. Currently, you can group only by SUBSCRIPTION_ID.

May throw LimitExceededException. May throw DataUnavailableException. May throw InvalidNextTokenException.

Parameter timePeriod : Sets the start and end dates for retrieving RI utilization. The start date is inclusive, but the end date is exclusive. For example, if start is 2017-01-01 and end is 2017-05-01, then the cost and usage data is retrieved from 2017-01-01 up to and including 2017-04-30 but not including 2017-05-01.

Parameter filter : Filters utilization data by dimensions. You can filter by the following dimensions:

  • AZ
  • CACHE_ENGINE
  • DEPLOYMENT_OPTION
  • INSTANCE_TYPE
  • LINKED_ACCOUNT
  • OPERATING_SYSTEM
  • PLATFORM
  • REGION
  • SERVICE
  • SCOPE
  • TENANCY
GetReservationUtilization uses the same Expression object as the other operations, but only AND is supported among each dimension, and nesting is supported up to only one level deep. If there are multiple values for a dimension, they are OR'd together.

Parameter granularity : If GroupBy is set, Granularity can't be set. If Granularity isn't set, the response object doesn't include Granularity, either MONTHLY or DAILY. If both GroupBy and Granularity aren't set, GetReservationUtilization defaults to DAILY.

The GetReservationUtilization operation supports only DAILY and MONTHLY granularities.

Parameter groupBy : Groups only by SUBSCRIPTION_ID. Metadata is included.

Parameter nextPageToken : The token to retrieve the next set of results. AWS provides the token when the response from a previous call has more results than the maximum page size.

Implementation

Future<GetReservationUtilizationResponse> getReservationUtilization({
  required DateInterval timePeriod,
  Expression? filter,
  Granularity? granularity,
  List<GroupDefinition>? groupBy,
  String? nextPageToken,
}) async {
  ArgumentError.checkNotNull(timePeriod, 'timePeriod');
  _s.validateStringLength(
    'nextPageToken',
    nextPageToken,
    0,
    8192,
  );
  final headers = <String, String>{
    'Content-Type': 'application/x-amz-json-1.1',
    'X-Amz-Target': 'AWSInsightsIndexService.GetReservationUtilization'
  };
  final jsonResponse = await _protocol.send(
    method: 'POST',
    requestUri: '/',
    exceptionFnMap: _exceptionFns,
    // TODO queryParams
    headers: headers,
    payload: {
      'TimePeriod': timePeriod,
      if (filter != null) 'Filter': filter,
      if (granularity != null) 'Granularity': granularity.toValue(),
      if (groupBy != null) 'GroupBy': groupBy,
      if (nextPageToken != null) 'NextPageToken': nextPageToken,
    },
  );

  return GetReservationUtilizationResponse.fromJson(jsonResponse.body);
