Monitor virtual appliances
The monitoring system displays VM metrics and the user can configure alerts to trigger actions if certain conditions are met within virtual appliances. If your virtual datacenter supports monitoring, but you don't see any metrics for your virtual appliance, you may need to edit your VMs and configure monitoring on the VM monitoring tab. See VM monitoring and metrics

Manage scaling groups
To configure an automatic response to changing demands for resources, you can scale out VMs, which is also called horizontal autoscaling. To scale out, the platform clones the base VM and deploys the clones. To scale in, the platform will delete clone VMs but it will just undeploy the base VM. Scaling operations are subject to all standard platform constraints, such as privileges and allocation limits.

To use autoscaling do these steps:
- Create a base VM, which can be deployed or undeployed
- Define a scaling group with rules for scaling the VM
- Create an action plan with scaling actions for the VM. Create triggers for the action plan, which are either monitoring alerts for virtual appliances or schedules for planned scaling
