【问题描述】：

每个实例都收到一封未通过状态检查的电子邮件。我想为所有状态检查收到一封电子邮件。

这是我的代码：

import boto3
import smtplib

client = boto3.client("ec2")
clientsns = boto3.client("sns")

status = client.describe_instance_status(IncludeAllInstances = True)
#failed_instances = []
for i in status["InstanceStatuses"]:
#        failed_instances.append(i['Instance')]      
        in_status = i['InstanceStatus']['Details'][0]['Status']
        sys_status = i['SystemStatus']['Details'][0]['Status']
        
        # check statuses failed instances
        if ((in_status != 'passed') or (sys_status != 'passed')):
             msg = f'The following instances failed status checks, i["InstanceId"]'
             clientsns.publish(TopicArn='arn:aws:sns:us-west-1:462518063038:test',Message=msg)

【参考方案1】：

试试这样的：

import boto3
import botocore
from boto3 import Session

boto3.setup_default_session(profile_name='account2')

def get_tag(tags, key='Name'):
    if not tags: return ''
    for tag in tags:
        if tag['Key'] == key:
            return tag['Value']
    return ''

client = boto3.client("ec2")
conn = boto3.resource('ec2')
#instances = conn.instances.filter()
instances = conn.instances.filter(
        Filters=['Name': 'instance-state-name', 'Values': ['running']])

filter_for = 
    "running": ["Name": "instance-state-name", "Values": ["running"]],


ec2instance = client.describe_instance_status(IncludeAllInstances = True, Filters=filter_for["running"])

failed_instances = []
for i in ec2instance["InstanceStatuses"]:    
        in_status = i['InstanceStatus']['Details'][0]['Status']
        sys_status = i['SystemStatus']['Details'][0]['Status']
        
        # check statuses failed instances
        if ((in_status != 'passed') or (sys_status != 'passed')):
             failed_instances.append(i["InstanceId"])

if len(failed_instances)>0:
 #   new_line = '\n'
 #   msg = f'The following instances failed status checks:new_line new_line.join(failed_instances)'
 #   #msg = f'The following instances failed status checks, failed_instances'
 
 #   clientsns.publish(TopicArn='arn:aws:sns:us-west-1:462518063038:test',Message=msg)

for j in failed_instances:
  instance = [x for x in list(instances) if x.id == j][0]
  instance_name = get_tag(instance.tags)        
  print (instance_name, instance.id, instance.instance_type) 

【讨论】：

谢谢。如何将每个实例放在不同的行上

只需使用换行符\n。查看编辑后的答案

您好，我知道如何打印出实例的 TAG 名称。标签中的键值是名称和值

查看编辑后的答案。此外，SO 中还有其他问题更详细。

这是否意味着我需要双循环？我想打印出实例名称，状态检查失败的实例 ID
