To help you detect and address changing demand for resources, the virtual appliance has Monitoring and Control features. Go to Virtual datacenters, select a virtual appliance and then select the Monitoring or Control tabs.

Basic control and scaling 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. Abiquo alerts can 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
For horizontal autoscaling, create a scaling group for a VM with rules to define how the platform should scale it out. You can then include scaling operations in an action plan.
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.
