Managing alarm notifications

• Note AWS Lambda retries function errors twice. If the function doesn't have enough capacity to handle all incoming requests, events might wait in the queue for hours or days to be sent to the function. You can configure an undelivered-message queue (DLQ) on the function to capture events that weren't successfully processed. For more information, see Asynchronous invocation in the AWS Lambda Developer Guide.
