Abiquo 4.7

Skip to end of metadata
Go to start of metadata

Before you begin:

  1. Configure the base VM that will be scaled
  2. Ensure that you have enough resources in your virtual datacenter to deploy up to the maximum number of cloned VMs, especially IP addresses

To create a scaling group:

  1. Go to Virtual datacenters → Virtual appliances
  2. Select the base VM, and from the menu on the VM icon, select the Create scaling group option
  3. Enter the scaling parameters and rules
  4. Click Save

 

 

FieldDescription
NameName of the scaling group 
Default cooldownPeriod of time to wait from the start of one scaling operation before allowing another scaling operation
Minimum running virtual machines

The minimum running VMs that Abiquo must maintain in the scaling group. The value must be greater than or equal to zero, where zero means that the base machine is not deployed

Maximum running virtual machinesThe maximum running VMs that Abiquo must maintain in the scaling group
Keep virtual machines in the same layerSelect this option to maintain VM anti-affinity layers when autoscaling
Disable workflowAdministrators with the privilege to Manage workflow for scaling groups can use this option to disable workflow or enable it as required.
Create in maintenance modeSelect this option to create the scaling group with maintenance mode ON, for example, to delay the automatic deployment of VMs to meet the minimum size
Create autoscaling actionCreate basic operations to scale in and scale out, with triggers based on metrics and alarm conditions.
Scaling rulesScaling rules describe how Abiquo will behave when a scaling event is triggered, for example, by an alert or a schedule.

Scaling rules

FieldDescription
VMsFor a scale out rule, the number of times to clone the base machine and deploy each clone for each scaling step. For a scale in rule, the number of machines to remove from the scaling group (Abiquo will delete clone machines and undeploy the base machine)
CooldownThe cooldown time to wait between scaling operations under this rule
StartDate and time to start the time range when scaling triggers will start a scaling operation under this rule. The time range must be unique and cannot overlap with other rules with the same scaling direction. If there is no time range, then this is a default scaling rule.
EndDate and time that is the end of the time range when scaling triggers will start a scaling operation. The time range must be unique and cannot overlap with other rules with the same scaling direction. If there is no time range, then this is a default scaling rule

When you save the scaling group, Abiquo will mark the VM icon with the scaling group symbol and display the scaling group name. If the minimum number of deployed VMs are not present and the scaling group is not in maintenance, Abiquo will create clones of the base VM and deploy them to reach the minimum size. The number in the bottom right-hand corner of the icon is the number of running VMs in the scaling group, including the base VM.

To open the scaling group and check its parameters, click the scaling group symbol in the top right-hand corner of the VM icon.
