To help you detect and address changing demand for resources, the platform's Control features include monitoring alerts with notifications, action plans for automation, and autoscaling. These features may depend on the configuration of VM monitoring and metrics and Manage cloud alarms v44, so you may like to set these up first. To use scaling, you should also define scaling groups for the VMs you want to scale, see Define scaling for a VM. The Control view has Alert and Action plans tabs.
Basic control and scaling concepts
Before you work with control features, please familiarize yourself with these basic concepts.
Alarms
An alarm activates when a metric passes a certain threshold. If you imagine a dashboard for your metrics, alarms are like red lights that light up when conditions change, for example, when there is a problem.
Alerts
Alerts enable you to configure notifications or actions for the VMs in a virtual appliance. Alerts are like a worker monitoring a group of alarms; when all the lights for the group are lit up, the alert is activated. Alerts can notify users and trigger action plans.
Action plans
A sequence of actions to perform on a virtual appliance. An action plan is run by a trigger.
Trigger
A trigger is an alert or a schedule that will run the action plan, for example, during times of increased demand.
Scaling group
To scale out a VM by cloning it, define a scaling group for the VM with rules to specify how the platform should scale it out. You can then include scaling operations in an action plan to automate scaling.
Vertical scaling
Vertical scaling means adding more resources to an existing VM, for example, boosting your CPU and or RAM capacity.
Horizontal scaling
Horizontal scaling means deploying more VMs when you need more resources.
Create Alerts and Alarms
To configure alerts, go to Control view → Alerts.

Manage action plans and triggers
To enable more control over cloud operations, users can create action plans to run tasks on VMs and scaling groups, and to run general tasks.
...
Action plans are an important automation functionality on the platform. They can combine tasks for VMs in different providers and have multiple triggers including alerts from custom metrics or built-in metrics. Each VM or scaling group can have multiple action plans.
Create an action plan
Before you create an action plan, you will probably want to create at least one VM.
...
To run the action plan automatically, go to the Triggers tab and create an alert or schedule trigger.
Run an action plan now
When you have added some actions and saved the action plan, you can run the action plan immediately to test it. Edit the action plan and click the Execute action plan button, which is beside the + add button to create a new action.
...
Abiquo recommends that you run an action plan manually to test it before you create a trigger to run it automatically.
Create a trigger
The platform supports two types of triggers to run action plans: Alerts and Schedules.
To run your action plan based on metrics, you can select an existing alert to trigger an Action plan. Click the + Add button and select the Alert. For details about creating an alert, see #Create Alerts and Alarms
To run your action plan automatically at selected dates and times, create a schedule trigger.

Delete an action plan
If you delete an action plan, Abiquo will also delete the schedule associated with that action plan.
Scale out VMs
As an automatic response to changing demands for resources, the platform can scale out by cloning a master VM. And it can scale in, by deleting clone machines and undeploying the master VM.
