This document is part of the Abiquo walkthrough and it describes the Control view. |
The Control tab enables Users users to detect and automatically meet changing demands for resources on the platform. The foundations of the control system are metrics, which can be standard metrics from a provider or hypervisor, or custom metrics that the user creates and populates with values using the Abiquo API. Administrators can create custom metrics for infrastructure and all users can create custom metrics for virtual resources.
...
There is an Alarms tab in the Infrastructure view for data centers, racks, physical machines, and VM entities on the Infrastructure path. And there is another Alarms tab in the Virtual datacenters view, for virtual resource entities, including VDCs, VApps, VMs, and scaling groups.
Screenshot: Create alarm - the platform uses alarms to detect if a metric passes a threshold. Users create alarms for metrics by specifying the conditions with which to evaluate the metric
...
Screenshot: Alerts - Users can create Alerts alerts on the Control tab. An Alert can notify users or trigger an action plan when a group of alarms are triggered, which means that a group of metrics passed certain thresholds.
...
Users can define Scaling Groups scaling groups with rules for how to add more VMs or retire them. When the platform scales out, it will clone VMs according to the scaling rules.

...
Scaling groups let you automate the response to resource demands of their applications and increment resources or VMs using action plans and scaling groups.
- Create a VM and enable metrics
- Create a scaling group for the VM with scaling rules and click Add
- If the scaling group is in maintenance mode, disable maintenance mode
...
When the user defines a scaling group, they can automatically define a scaling action. The platform will automatically create the appropriate alarms, alerts, and action plan with scaling actions.
Users can also create action plans to define a sequence of actions to perform at a scheduled time. Examples of actions are adding more resources to a VM, deploy, and power actions, as well as adding more VMs to a scaling group, or scaling in to retire VMs.

The alternative to an Interval schedule for running an action plan. An is an Advanced schedule, which is a calendar schedule, as shown below the Interval schedule

.
Also in the Control view, you can manage multicloud budgets, that can trigger notifications or alerts, and thus run action plans, for example, to deploy additional resources.
...
In the Control view you will also find the search and reporting functions of the multicloud tagging feature that lets you inventory resources much more easily. And you can create tag policies to ensure users work with the correct tags and values. The tag Compliance report page will inform you of tags that do not comply with your tag policies.
