Research direction

Start by locating the ScheduledLambda implementation and review the linked AWS Lambda Dead Letter Queue documentation. Change the alarm behavior so transient function errors do not trigger alarms, while messages sent to the Dead Letter Queue do; verify the resulting CloudFormation template and alarm configuration.

Description

enhancement p4

Right now ScheduledLambda alarms on every single error of a lambda function. I propose to change this to never alarm on errors but instead use a Dead Letter Queue and alarm whenever something lands in there. This will make ScheduledLambda alarms less noisy to transient errors, while still retaining the visibility into persistent problems.
