AWS SDK for Python(Boto3)을 통해 EC2의 CPU 사용률을 가져오는 방법

차리다

코드

import boto3
import requests
import datetime
import dateutil.tz

region = requests.get('http://169.254.169.254/latest/meta-data/local-hostname').text.split('.')[1]
instance_id = requests.get('http://169.254.169.254/latest/meta-data/instance-id').text

client = boto3.client("cloudwatch", region_name=region)

response = client.get_metric_statistics(
        Namespace='AWS/EC2',
        MetricName='CPUUtilization',
        Dimensions=[
          {
            'Name': 'InstanceId',
            'Value': instance_id
          },
        ],
        StartTime=datetime.datetime.utcnow() - datetime.timedelta(seconds=600),
        EndTime=datetime.datetime.utcnow(),
        Period=300,
        Statistics=['Average']
)

for res in response['Messages']:
  if 'Body' in res:
    print(res['Body'])
