After enabling autoscaling and creating at least one alert, perform the following steps to create a scaling policy.

Steps

1. In the Policy Configuration section, provide the following information:

   Parameter	Description
   Enter policy name	Enter a unique name for the policy.

   Enter number or percentage	Enter a number defining how many or what percentage of nodes to add or remove. If the action selected is “set”, this defines the number of nodes that a host group will be set to after scaling.
