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.
|Metric||A built-in metric that is provided by a hypervisor or provider (e.g. CPU usage) or a custom metric that the user creates and populates using API calls|
|Alarm||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. See Manage cloud alarms and Infrastructure Alarms|
|Alert||An alert enables you to configure notifications or actions from alarms. 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 trigger action plans. See Control View|
|Action plans||A sequence of actions to perform on entities on the platform, such as VMs or scaling groups. 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 scaling up, adding more resources to an existing VM, for example, boosting your CPU and or RAM capacity.|
|Horizontal scaling||Horizontal scaling means scaling out, deploying more VMs when you need more resources.|
The platform's alerts feature enables you to track and act upon changes in your cloud environment. To configure Alerts do these steps:
Go to Alarms. Create alarms for built-in metrics, scaling group metrics, and custom metrics as required
You can perform cloud bursting with the platform's Control features. Cloud bursting is automatically deploying new resources in any part of your hybrid cloud environment to meet a peak in demand for resources. Here is a brief outline of how to configure cloud bursting with VM automation.
Define scaling groups for VMs. The base VM can be deployed or undeployed. See Manage Scaling Groups
Create alarms for built-in metrics, scaling group metrics, or custom metrics. See Custom Metrics Resources. To work with auto-scaling, we recommend that you create alarms for both the high threshold, when you will require more resources, and the low threshold, when these resources can be retired
