This section covers how to work with the auto scaling groups in the Eucalyptus Management
Console.
Scaling Groups Landing Page
This page allows you to view a list of your scaling groups, create new scaling groups, and edit existing scaling groups. Use the scroll bar to view additional scaling groups not in the browser's current view.
Create a Scaling Group - General
This page allows you to create a scaling group. An Auto Scaling group defines the parameters for the Eucalyptus instances that are used for scaling, as well as the minimum, maximum, and the desired number of instances to use for Auto Scaling your application. In order to create a scaling group, you must first have a launch configuration created. For more information on Auto Scaling, see Using Auto Scaling in the Eucalyptus User Guide.
Create a Scaling Group - Membership
This page allows you to create a scaling group. An Auto Scaling group defines the parameters for the Eucalyptus instances that are used for scaling, as well as the minimum, maximum, and the desired number of instances to use for Auto Scaling your application. In order to create a scaling group, you must first have a launch configuration created. For more information on Auto Scaling, see Using Auto Scaling in the Eucalyptus User Guide.
Scaling Group Detail - General
An Auto Scaling group defines the parameters for the Eucalyptus instances that are used for scaling, as well as the minimum, maximum, and desired number of instances to use for Auto Scaling your application. This page allows you to view and edit a scaling group. For more information on Auto Scaling, see Using Auto Scaling in the Eucalyptus User Guide.
Scaling Group Detail - Scaling History
This tab displays a running history of scaling activities occurring on the selected scaling group. All the information displayed is non-editable:
Scaling Group Detail - Scaling Policies
This tab allows you to view and manage the policies applied to the selected scaling group. Also, it allows you to add scaling policies to your scaling group.
Scaling Group Detail - Instances
An Auto Scaling group defines the parameters for the Eucalyptus instances that are used for scaling, as well as the minimum, maximum, and desired number of instances to use for Auto Scaling your application. This tab allows you to view and manage the instances associated with the selected scaling group.
Create Scaling Policy
An Auto Scaling policy defines how to perform scaling actions in response to CloudWatch alarms. Auto scaling policies can either scale-in, which terminates instances in your Auto Scaling group, or scale-out, which will launch new instances in your Auto Scaling group. For more information on Auto Scaling, see Using Auto Scaling in the Eucalyptus User Guide.
Delete Scaling Group
This dialog box allows you to confirm or cancel a scaling group delete operation.
Create CloudWatch Alarm
Auto Scaling uses CloudWatch alarms to trigger scaling actions. An alarm watches a single metric (for example: CPU utilization) over a time period you set, and performs one or more actions based on the value of the metric relative to a given threshold. CloudWatch alarms will not invoke actions just because they are in a particular state. For more information, see the Eucalyptus CloudWatch documentation in the Eucalyptus User Guide.
