Email Alerts on Cloud Function Exception

I'm new to the GCP environment.

Scenario: I have Created a Cloud Function which triggers Based on Message Published to the Topic.

Condition: Every Message Published Compulsory to have. Message body and 2 Attributes init.

Cloud Function Should check whether the message and Attribute are there (Non-empty). If any of the above are empty Cloud Function must fail Raise an Email Alert.

**Sample Code**

import base64
import sys

def hello_pubsub(event, context):
 pubsub_message = base64.b64decode(event['data']).decode('utf-8')
 print(pubsub_message)
 pubsub_attributes = event['attributes']
 transaction_id = event['attributes']['transaction_id']
 print(transaction_id)
 refined_paths = event['attributes']['refined_paths']
 print(refined_paths)
 pubsub_timestamp = context.timestamp

 #Check whether variable are set or not.
 pubsub_message_status = bool(pubsub_message)
 transaction_id_status = bool(transaction_id)
 refined_paths_status  = bool(refined_paths)

 if(pubsub_message_status == False or transaction_id_status == False or refined_paths_status == False):
  raise RuntimeError("Message Content and Attribute are Empty")

I tried this way Cloud Function is Deployed Preroroperly but NameError is Raised (Adding Photos of CF logsenter image description here

You can use Cloud Monitoring to set up email alerting based on a Pub/Sub message output:

  1. In the Cloud Console, use the project picker to select your Google Cloud project, and then select Monitoring, or click the following button:

Go to Monitoring

  1. In the Monitoring navigation pane, click notifications Alerting.

Click Edit notification channels.

To add a new notification channel, locate the channel type, click Add new, and then follow the channel-specific instructions contained in the following table:

refer to the Pub/Sub table

Yes, you need to perform the business check in your code. When you find something wrong, write a log entry.

Then, create log based metrics on this specific log entry and an alert on this metric

If the alerting isn't a concern, you can also add a filter on PubSub subscription (only at creation time) to only receive the valid messages (with the 2 attributes that you want, body content can't be checked)
