为什么成本资源管理器客户端显示错误的结果，当我有AWS学分？

Question

当使用AWS控制台--> AWS成本管理->成本资源管理器--我得到以下值：

​

​

当我使用@aws-sdk/client-cost-explorer时，我会得到'EC2 - Other‘和'Amazon’的不同结果。

配置：

import { CostExplorerClient, GetCostAndUsageCommand } from '@aws-sdk/client-cost-explorer';

const client = new CostExplorerClient({
        region,
        credentials: {
          accessKeyId,
          secretAccessKey
        }
      });
    
      const params = {
        TimePeriod: {
          Start: startDate,
          End: endDate
        },
        Filter: {
         Dimensions: {
           Key: 'SERVICE',
           Values: [
             'EC2 - Other', 'Amazon ElastiCache'
           ]
         }
        },
        GroupBy: [
          {
            Type: 'DIMENSION',
            Key: 'SERVICE',
          },
        ],
        Granularity: 'DAILY',
        Metrics: [
          'BLENDED_COST',
          'UNBLENDED_COST',
          'AMORTIZED_COST', 
          'NET_AMORTIZED_COST',             
     ] 
      };
      const command = new GetCostAndUsageCommand(params);
      try {
        const data = await client.send(command);
        log.info(data);

其结果是：

GroupDefinitions: [
    {
      "Key": "AZ",
      "Type": "DIMENSION"
    },
    {
      "Key": "SERVICE",
      "Type": "DIMENSION"
    }
  ]

如您所见，“AmazonEC2”的数量对于所有度量都是正确的，但是EC2-其他的数量对于所有度量都是错误的。

我们的帐户目前使用AWS信用。

我正在寻找用于此SDK的正确参数，以便接收每个服务的日/月使用量。

默认情况下，控制台中的成本资源管理器UI应用了一个筛选器，其中不包括 refund 和 credit 收费类型(您可以在筛选器列表的中间看到它)。

在使用AWS信用时，当前的GetCostAndUsageCommand将包括降低Amount值的信用。

您将需要复制相同的排除筛选器，它已经应用于UI中。，这将增加您的Amount值，与控制台中显示的内容一致。

您可以使用NOT 表达式排除退款和/或抵免(视情况而定)。这已经从GetCostAndUsageCommandInput文档中链接到。

尝试：

const params = {
    TimePeriod: {
        Start: startDate,
        End: endDate
    },
    Filter: {
        Not: {
            Dimensions: {
                Key: "RECORD_TYPE",
                Values: ["Refund", "Credit"]
            }
        },
        Dimensions: {
            Key: 'SERVICE',
            Values: [
                'EC2 - Other', 'Amazon ElastiCache'
            ]
        }
    },
    GroupBy: [{
        Type: 'DIMENSION',
        Key: 'SERVICE',
    }, ],
    Granularity: 'DAILY',
    Metrics: [
        'BLENDED_COST',
        'UNBLENDED_COST',
        'AMORTIZED_COST',
        'NET_AMORTIZED_COST',
    ]
};
