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 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 also 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.
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. In Abiquo, this is configured with a scaling group and scaling actions, which are part of an action plan that is run by a trigger.

In order to create alarms that are not associated with alerts, edit your VMs and configure alarms for VM metrics. See VM Alarms.

The muted alerts have an alert "speaker" symbol without sound waves. The alerts that are not muted have an alert symbol with sound waves.

VMs
Before you create an alert for the VMs in a virtual appliance, remember to do the following steps when editing the VMs:
...
- At the top of the Alerts panel, click the + add button
- Enter the alarm details.
- Abiquo recommends that you enter a name that will uniquely identify the alarm
- See VM Alarms for details of the Alarm fields, which are the same as on the Alarms tab of the virtual machineVM
- To save, click the floppy disk icon. The platform will create the alarm
- Remember to add your alarm to an alert because the platform will not do it automatically!
- To manage an alarm that is not in an alert, go to the VM Alarms section, which requires the Access alarms section privilege

To enable more control over cloud operations, users can create virtual machine VM action plans to run tasks for virtual machines VMs and Docker workloads.

Virtual machine VM action plans are for both private and public cloud and are an important autoscaling functionality on the platform. A VM can have mutliple action plans

Before you create an action plan, first create a virtual machineVM. To create an action plan:
