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.

needs to be crossed in order to trigger a scale-out
recommendation.

In the Scale-In
field, you can adjust the previously configured
metrics and defined unit thresholds that trigger a scale-in
recommendation.

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.
