我正在嘗試編寫一個 Python/BOTO3 腳本來獲取 us-east-1、us-west-1、ap-southeast-1 區域中的所有實例。我試圖收集的信息是：實例編號實例類型附加到實例的 IAM 角色列表項 所有告警的狀態我的目標是將其輸出到 CSV 文件。目前我已經走了這么遠，我有點卡住了，一些幫助將不勝感激：import boto3from collections import defaultdictregions = [ 'ap-southeast-1', 'us-west-1', 'us-east-1',]ec2 = boto3.resource('ec2', region_name="us-east-2")running_instances = ec2.instances.filter(Filters=[{ 'Name': 'instance-state-name', 'Values': ['running']}])ec2info = defaultdict()for instance in running_instances: ec2info[instance.id] = { 'Instance ID': instance.id, 'State': instance.state['Name'], 'Instance Type': instance.instance_type, }attributes = ['Instance ID', 'State', "Instance Type"]for instance_id, instance in ec2info.items(): for key in attributes: print("{0}: {1}".format(key, instance[key])) print("------")```Thanks in advance :-)

獲取所有警報是一個棘手的部分，因為除非您預先了解它們，否則很難找到所有警報。盡管如此，我還是以開發演示代碼為例CPUUtilization：
import boto3
regions = [
'ap-southeast-1',
'us-west-1',
'us-east-1',
]
for region in regions:
ec2 = boto3.resource('ec2', region_name=region)
running_instances = ec2.instances.filter(Filters=[{
'Name': 'instance-state-name',
'Values': ['running']}])
cw = boto3.client('cloudwatch', region_name=region)
for instance in running_instances:
instance_profile = 'N/A';
if instance.iam_instance_profile:
instance_profile = instance.iam_instance_profile['Arn']
print(region,
instance.id,
instance.instance_type,
instance_profile)
alarms = cw.describe_alarms_for_metric(
Namespace='AWS/EC2',
MetricName='CPUUtilization',
Dimensions=[
{
'Name': 'InstanceId',
'Value': instance.id
}]
)
if 'MetricAlarms' in alarms:
for alarm in alarms['MetricAlarms']:
print(f" - {alarm['AlarmName']}, {alarm['StateValue']}")
示例輸出：
us-west-1 i-0d45a86caf2ee0e71 t2.micro arn:aws:iam::353693526480:instance-profile/InstanceRole
- awsec2-i-0d45a86caf2ee0e71-CPU-Utilization, OK
us-east-1 i-0f7cd6d6123e6c47e t2.micro N/A
