amazon-web-services - cloudwatch 命令 get-metric-data

我无法通过此命令获取指标数据。

aws cloudwatch get-metric-data --metric-data-queries jsonfile.json \
   --start-time 2019-02-01T10:40:0000 --end-time 2019-02-27T14:12:0000

显示以下错误。

Error parsing parameter '--metric-data-queries': Expected: '=', received: 'EOF' for input:

jsonfile.json

在这里，jsonfile.json包含我的查询，定义如下。

[
    {
        "Id": "MyRequest",
        "MetricStat": {
            "Metric": {
                "Namespace": "AWS/EBS",
                "MetricName": "VolumeReadBytes",
                "Dimensions": [
                    {
                        "Name": "VolumeId",
                        "Value": "vol-******420********"
                    }
                ]
            },
            "Period": "3600",
            "Stat": "Average",
            "Unit": "Bytes"
        },
        "Label": "myRequestLabel",
        "ReturnData": "true"
    }
]

最佳答案

我认为您需要运行；

    aws cloudwatch get-metric-data --cli-input-json file://jsonfile.json

jsonfile.json的内容应如下所示；

{
    "MetricDataQueries": [
        {
            "Id": "myRequest",
            "MetricStat": {
                "Metric": {
                    "Namespace": "AWS/EBS",
                    "MetricName": "VolumeReadBytes",
                    "Dimensions": [
                        {
                            "Name": "VolumeId",
                            "Value": "vol-******420********"
                        }
                    ]
                },
                "Period": 3600,
                "Stat": "Average",
                "Unit": "Bytes"
            },
            "Label": "myRequestLabel",
            "ReturnData": true
        }
    ],
    "StartTime": "2019-02-01T10:40:0000",
    "EndTime": "2019-02-27T14:12:0000"
}
