Introduction to autoscaling
...
Go to Virtual datacenters → Virtual appliances
On the VM icon, from the options menu, select Define scaling group
Enter the scaling parameters
For the Default cooldown, enter the period of time to wait from the start of one scaling operation before allowing another scaling operation
For the Minimum running virtual machines 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
The option to Keep virtual machines in the same layer can maintain VM anti-affinity layers when autoscaling
Administrators with the privilege to Manage workflow for scaling groups can Disable workflow or enable it as required
Optionally, select Create in maintenance mode to delay the start of autoscaling, and the automatic deployment of VMs to meet the minimum size
Select the option to Create autoscaling action to create basic operations to scale in and scale out, with triggers based on metrics and alarm conditions.
Create scaling rules
For Scale out rules, enter the number of VMs to Add. This isthe number of times to clone the base VM and deploy each clone for each scaling step
For Scale in rules, enter the number of VMs to Remove. Abiquo will delete clone machines and undeploy the base machine
If there is no time range, then this is a default scaling rule. A time range must be unique and cannot overlap with other rules with the same scaling direction.
Click Save
