Question

是否可以通过boto python API获取EC2实例中的vCPU（内核）数量？

到目前为止，我的代码是：

在boto3中找到了它：

import boto3     
ec2 = boto3.resource('ec2', region_name=REGION_NAME)
instance = ec2.Instance(id)
instance.cpu_options.get(u'CoreCount','1')

返回的是我的物理核数，但是通过htop，我可以看到我的核芯数是VCPU的两倍，是否总是这样？也许与ThreadsPerCore的数量有关？

我是用这种方式完成的，需要最新版本的boto3：

import boto3
# You may have to update boto3 to get this to work, describe_instance_types is quite new:
# pip install boto3 --upgrade
ec2 = boto3.client('ec2')

reservations = ec2.describe_instances()['Reservations']
vcpus = 0
for reservation in reservations:
    for instance in reservation['Instances']:
        instance_id = instance['InstanceId']
        instance_type_name = instance['InstanceType']
        instance_type = ec2.describe_instance_types(InstanceTypes=[instance_type_name])
        current_vcpu_count = instance_type['InstanceTypes'][0]['VCpuInfo']['DefaultVCpus']
        print(f'{instance_id} - {instance_type_name} - {current_vcpu_count}')
        vcpus += current_vcpu_count

print(vcpus)
