AWS-SDK CloudWatch MaxQueryTimerangeExceed

我是AWS SDK（和nodejs）的新手，我正在尝试让CloudWatch的GetMetricData工作。我使用简单的CloudWatch查询来获取实例的CPU利用率。但是无论我做什么，我一直在

{
  ResponseMetadata: { RequestId: '5253fbfc-5aa2-4dfb-871b-1453f8610d80' },
  MetricDataResults: [
    {
      Id: 'q1',
      Label: 'q1',
      Timestamps: [],
      Values: [],
      StatusCode: 'Complete',
      Messages: []
    }
  ],
  Messages: [
    {
      Code: 'MaxQueryTimeRangeExceeded',
      Value: 'Max time window exceeded for query'
    }
  ]
}

这里得到这个是我的代码

const AWS = require("aws-sdk");
AWS.config.loadFromPath("./config.json");

var cloudwatch = new AWS.CloudWatch({apiVersion: "2010-08-01"});

var params = {

    StartTime: new Date('june 06, 2022 17:30'),
    EndTime: new Date('june 06, 2022 18:00'), 
    MetricDataQueries: [ 
      {
        Id: 'q1', 
        Expression: "SELECT AVG(CPUUtilization) FROM SCHEMA(\"AWS/EC2\", InstanceId) WHERE InstanceId = 'i-**********'",
        Period: '600'
      },
    ],
    
  };
  cloudwatch.getMetricData(params, function(err, data) {
    if (err) console.log(err, err.stack); 
    else     console.log(data);           
  });

I am new to AWS SDK (and nodejs) and I am trying to get cloudwatch's getMetricData to work. Im using a simple Cloudwatch query to grab the CPU utilization of an instance. But no matter what I do, I just keep getting this

{
  ResponseMetadata: { RequestId: '5253fbfc-5aa2-4dfb-871b-1453f8610d80' },
  MetricDataResults: [
    {
      Id: 'q1',
      Label: 'q1',
      Timestamps: [],
      Values: [],
      StatusCode: 'Complete',
      Messages: []
    }
  ],
  Messages: [
    {
      Code: 'MaxQueryTimeRangeExceeded',
      Value: 'Max time window exceeded for query'
    }
  ]
}

here is my code

const AWS = require("aws-sdk");
AWS.config.loadFromPath("./config.json");

var cloudwatch = new AWS.CloudWatch({apiVersion: "2010-08-01"});

var params = {

    StartTime: new Date('june 06, 2022 17:30'),
    EndTime: new Date('june 06, 2022 18:00'), 
    MetricDataQueries: [ 
      {
        Id: 'q1', 
        Expression: "SELECT AVG(CPUUtilization) FROM SCHEMA(\"AWS/EC2\", InstanceId) WHERE InstanceId = 'i-**********'",
        Period: '600'
      },
    ],
    
  };
  cloudwatch.getMetricData(params, function(err, data) {
    if (err) console.log(err, err.stack); 
    else     console.log(data);           
  });

您只能使用选择...语法请求最新的3个小时数据。

来自 docs

指标见解查询只能查询最近三个小时
公制数据。

看起来您只为一个实例获得cpuutilization。您可以使用metricstat对象获得它。这样的事情：

var params = {

    StartTime: new Date('june 06, 2022 17:30'),
    EndTime: new Date('june 06, 2022 18:00'), 
    MetricDataQueries: [ 
      {
      Id: 'm1',
      Label: 'CPUUtilization',
      MetricStat: {
        Metric: {
          Namespace: 'AWS/EC2',
          MetricName: 'CPUUtilization',
          Dimensions: [
            {
              Name: 'InstanceId',
              Value: 'i-xxxxxxxxxx'
            }
          ]
        },
        Period: '600',
        Stat: 'Average'
      }
    },
    ],
    
  };

You can only request the latest 3 hours of data using the SELECT ... syntax.

From docs,

Metrics Insights queries can query only the most recent three hours of
metric data.

Looks like you're only getting the CPUUtilization for a single instance. You can get that with the MetricStat object. Something like this:

var params = {

    StartTime: new Date('june 06, 2022 17:30'),
    EndTime: new Date('june 06, 2022 18:00'), 
    MetricDataQueries: [ 
      {
      Id: 'm1',
      Label: 'CPUUtilization',
      MetricStat: {
        Metric: {
          Namespace: 'AWS/EC2',
          MetricName: 'CPUUtilization',
          Dimensions: [
            {
              Name: 'InstanceId',
              Value: 'i-xxxxxxxxxx'
            }
          ]
        },
        Period: '600',
        Stat: 'Average'
      }
    },
    ],
    
  };
