Question

我有一个2个lambda函数，第一个得到一个实例ec2第二个检查ec2状态，我向第二个添加了一个计划事件，一个cron女巫每15分钟一次，所以现在我想验证我是否状态函数真的每15分钟调用一次，我已经检查了aws控制台中的触发器，但没有发生任何事情，我想知道我做错了什么？

这是我的handler.py文件

import sys
import schedule
import time
import logging


# Import local dependencies
sys.path.append('./site-packages')

import os
from pprint import pprint
import traceback
import json

import boto3
from botocore.exceptions import ClientError

def get_instance(client, event):


instance_name = None
instance_id = None
instance_state = None
error_message = None

# Get the instance name from the path
try:
    instance_name = event['pathParameters']['name']
    print( 'Instance Name: %s' % instance_name)
except:
    instance_name = None

if instance_name:
    r = client.describe_instances(
            Filters=[{'Name':'tag:Name', 'Values': [instance_name]}]
        )
    # AWS' boto3 api involves a lot of looping
    if len(r['Reservations']) > 0:
        for res in r['Reservations']:
            for ins in res['Instances']:
                ins_id = ins['InstanceId']
                ins_state = ins['State']['Name']
                if ins_state in ('shutting-down', 'terminated'):
                   error_message = 'No action taken. Instance %s is %s' %(ins_id, ins_state)
                else:
                    instance_id = ins_id
                    instance_state = ins_state
                break
    else:
        error_message = 'Unable to find instance with tag:Name - %s' %instance_name
else:
    error_message = 'No instance name specified'

print(error_message, instance_name, instance_id, instance_state)
return (error_message, instance_name, instance_id, instance_state)    

def ec2_status(event, context):
"""Take an instance tag:name via an API call and return its status"""
body = {}
status_code = 200

try:
    client = boto3.client('ec2')
    # Find the instance
    error, instance_name, instance_id, instance_state = get_instance(client, event)
    if error:
        body["message"] = error
    else:
        body["message"] = str(instance_id) + ' ' + str(instance_state)
except Exception as e:
    print(traceback.format_exc())
    status_code = 500
    body["message"] = str(e)

response = {
    "statusCode": status_code,
    "body": json.dumps(body)
}
return response
