Datadog Metrics Aren＆＃x27; t在我的Python应用程序上工作

Question

我在Datadog网站上提到了一些文档，但它仍然没有收集任何指标并将其发送到Datadog。该功能完美地执行，我认为我配置了正确的所有内容，但它不起作用。

这是我的应用程序代码，其中包括所需的模块和函数“包装器”，它提到要放在我的lambda函数模块上方，

from botocore.vendored import requests
import os
import smtplib
from datetime import datetime
from datadog_lambda.metric import lambda_metric
from datadog_lambda.wrapper import datadog_lambda_wrapper

lat = '33.4483771'
lon = '-112.0740373'
exclude = 'minutely,hourly,alerts'

url = (
    'https://api.openweathermap.org/data/2.5/onecall?' +
    'lat={lat}&lon={lon}&exclude={exclude}&appid={API_key}&units=imperial'
)

if os.path.isfile('.env'):
    from dotenv import load_dotenv
    load_dotenv()

def __send_email(msg: str) -> None:
    gmail_user = os.getenv('EMAIL_USER')
    gmail_password = os.getenv('EMAIL_PASSWORD')

    mail_from = gmail_user
    mail_to = gmail_user

    mail_subject = f'Weather Today {datetime.today().strftime("%m/%d/%Y")}'
    mail_message = f'Subject: {mail_subject}\n\n{msg}'

    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.starttls()
    server.login(gmail_user, gmail_password)
    server.sendmail(mail_from, mail_to, mail_message)
    server.close()

@datadog_lambda_wrapper
def handler(event, context):
    response = requests.get(url.format(
        lat=lat,
        lon=lon,
        exclude=exclude,
        API_key=os.getenv('WEATHER_API_KEY')
    ))

    data = response.json()

    rain_conditions = ['rain', 'thunderstorm', 'drizzle']
    snow_conditions = ['snow']

    today_weather = data['daily'][0]['weather'][0]['main'].lower()

    if today_weather in rain_conditions:
        msg = 'Pack an umbrella!'
    elif today_weather in snow_conditions:
        msg = 'Pack your snow boots!'
    else:
        msg = 'Clear skies today!'

    __send_email(msg) 

        # submit a custom metric
    lambda_metric(
        metric_name='coffee_house.order_value',
        value=12.45,
        tags=['product:latte', 'order:online']
    )
    
handler(None, None)

我创建了一个lambda层，并从他们的网站上找到了正确的ARN，

arn:aws:lambda:us-west-2:464622532012:layer:Datadog-Python37:56

我还为我的函数添加了一个名为dd_api_key的变量，称为dd_api_key文档并使用我的API密钥。非常感谢任何帮助或指导！
