```

    ["AWS/EC2", "CPUUtilization", "InstanceId", "i-0b...", { "period": 300, "stat": "Average" }]
]
```

      "resourceType": "AWS::EC2::Instance",
      "stat": "Average"
  }
]
```

How do I get resourceType metric data?

Answer

Hello.

There is no option to specify resourceType in get_metric_data().

Do you know the namespace where "resourceType": "AWS::EC2::Instance" is saved?  
If you know the namespace, there is a possibility that you can get it using get_metric_data().
