scale

Documentation

Overview

This package does not support edge based actions. Taking action on edges makes sense for alarms and other state tracking integrations, scaling operations should continue and repeat periodically while a monitor is in an ALARM state. This should ensure that the step increase or decrease will eventually reach some boundary beyond which operations stabilize.
