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.
Modify auto-scaling triggers
You have created a
service scaling group to manage your applications, and configured the metrics at which
you want the BIG-IQ to automatically create or remove BIG-IP VE devices.
Adjust the metrics
and unit thresholds that currently define a service scaling group's scaling rules. The
scaling rules define the trigger for the auto-scale recommendations of your service
scaling group, which either adds or removes BIG-IP VE devices.
The scale process is now triggered by the new alert
rules configured. Once the defined thresholds are crossed, you will receive a scale
recommendation alert. A scale recommendation will initiate a scale process, unless the
scale recommendation was triggered during the scale cool-down period.
