Modifying auto-scale triggers for your service scaling group
Your service scaling groups (SSG) triggers a scale event based on its auto-scaling rules. These rules consist of one or more metrics and a critical threshold that is sustained for over five minutes. When an SSG device's metrics violate one of the scale-out thresholds, a scale-out recommendation occurs. A scale-in recommendation occurs only when all metrics for a device drop below scale-in thresholds.
Each SSG has customized auto-scale rules. You can modify these rules, based on each SSG.
