To enable users to easily create the configuration associated with automatic scaling actions, there are new default values for the UI. The administrator can change the default values

configuration. When the user creates a scaling group, they can select the option to

...

average
maximum
minimum
sum
count (SampleCount)
dev (StandardDeviation)

...

notequal
greaterthan
greaterthanorequalto
lessthan
lessthanorequalto
trendup
trenddown

automatically create a scaling action. The user then selects the metric, and the UI presents the default values. The user can then optionally configure the thresholds for scaling out and scaling in, and so on. The platform will create all

...

alarms and alerts for the metrics, and an action plan to scale out

...

and scale in. The platform will replace "SCALINGGROUPNAME" with the name of the scaling group.

To change the default values,

Edit "client-config-default.json" and copy the full "client.autoscaling.action.default" attribute

To provide an example of the configuration, this is the default configuration for version 4.6.0. For the most recent configuration, please see Configure Abiquo UI
