If you already have a lambda function or other AWS service you want to monitor, you can jump ahead to Create a Slack Webhook.

Configure a CloudWatch to trigger our notification Lambda.Īs a test case, we will deploy a simple model that doubles a number and raises a ValueError if the input is not a number.

Create a Lambda function to send messages to Slack.

Deploy a simple linear model to a lambda function and connect it to an API gateway endpoint.

The magic happens when CloudWatch triggers our Notification Lambda to send a message to Slack whenever the log contains the text ERROR. So far, we have a standard model deployment on AWS Lambda. That Lambda model will return a prediction or an error to the API Gateway to send back to the user and will also write a log message to Cloud Watch logs. The user sends a request to API Gateway, which forwards that request to a model we have deployed with Lambda. AWS Architecture Icon and Slack Logo used in accordance with published use policies (1).

Slack Notifications from AWS CloudWatch Alarms.

Tracking AWS Lambda Functions error via Slack.

High-volume lambda functions are better off using one of the methods described in detail in the following resources:

While this method does involve CloudWatch, it does not require CloudWatch Alarms or any message queuing Service like SQS or Kenisis.Ī quick warning before we begin: If your Lambda function processes many requests per minute and begins to fail, your slack channel will blow up 💥 with error messages. With this method, you will get a notification containing the error message and traceback for each error directly in your slack channel, eliminating the need to dig into the logs to troubleshoot the error. Here I propose a more direct way of monitoring those periodic Lambda functions. There are many articles out there on monitoring Lambda errors using CloudWatch Alarms, but for periodic lambda jobs, this is both overly complex and doesn't provide much useful information in the notification other than that there was an error. A straightforward Python-based approach with the full error traceback sent to SlackĪs organizations develop, it is common to have ELT or batch inference jobs living in AWS Lambda that run periodically.
