当然，您可以使用AWS REST API（可通过SDKs或CLI获得） . 要获取实例指标，您需要使用EC2和CloudWatch API . 以下是AWS CLI的示例，其中包含您提供的文档"AWS related QOS Metrics"的指标：

Instance State ：

aws ec2 describe-instances --instance-ids i-999f9f99f999f99f9 --query "Reservations[*].Instances[*].[State]"

[
    [
        [
            {
                "Code": 16,
                "Name": "running"
            }
        ]
    ]
]

CPU Utilization (%) ：

aws cloudwatch get-metric-statistics --namespace AWS/EC2 --metric-name CPUUtilization  --period 60 --statistics Average --dimensions Name=InstanceId,Value=i-999f9f99f999f99f9 --start-time 2018-12-07T00:00:00 --end-time 2018-12-08T00:00:00

{
    "Label": "CPUUtilization",
    "Datapoints": [
        {
            "Timestamp": "2018-12-07T02:40:00Z",
            "Average": 0.0,
            "Unit": "Percent"
        },
        {
            "Timestamp": "2018-12-07T13:35:00Z",
            "Average": 1.0,

        },
        …
    ]
}

            "Average": 10.0,
            "Unit": "Count"
        },
        {

可以在here找到完整的可用指标列表 . 子页面包含特定服务的可用指标 . Here是EC2的页面 .

使用语言SDK时，您将获得几乎相同的数据 . 如您所见，CloudWatch只返回您查询过的带时间戳的指标列表 .
