Add CloudWatch Logs to To SNS Email

Question

I am trying to send alarm emails when some errors are thrown in an AWS Lambda function. I could configure CloudWatch Alarms to send emails via SNS topics by creating an Alarm. If I have a python exception, the alarm is thrown an email is sent. I can see the exception data in the Cloudwatch Logs. However, the emails do not contain the exception data. They are only showing up in the Logs as as follows:

{
"errorMessage": "Example Test Failure",
"errorType": "Exception",
"stackTrace": [
    [
    "/var/task/lambda_function.py",
    7,
    "lambda_handler",
    "raise Exception('Example Test Failure')"
    ]
  ]
}

Is there a way to add this errorMessage to the text of the SNS email ?

Answer 1

You can do that by streaming the CloudWatch logs to an AWS Lambda that sends a notification to SNS.
