Abiquo 5.1
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.
Concept | Description |
---|---|
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. |
Action plan | 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:
Create alarms for built-in metrics, scaling group metrics, and custom metrics as required
To create alarms, go to Virtual datacenters → select virtual datacenter → Alarms (see Manage cloud alarms) or Infrastructure → select datacenter → Alarms (see Infrastructure Alarms).
Select an entity, a metric, and a metric statistic and enter a threshold
Save the alarm
Create alerts to notify users
To create an alert:
Enter the alert details and assign alarms as described below
Click Save
Field | Description |
---|---|
Name | Name of the alert. The name can contain up to 128 characters |
Description | Describe the alert |
Muted | Select this checkbox to disable action when the alert is activated |
List of email addresses to notify when the alert activates. Click Add email to save an address |
Click the + add button to assign alarms to the alert.
You must assign at least one alarm to be able to save the alert. Select an existing alarm, or create a new alarm, and assign it to the alert. Repeat for the required alarms
You can filter the Alarms list by Metric and also if the alarm is Active or not.
To configure cloud bursting do these steps:
Create alarms for your critical values ofVM metrics, scaling group metrics, or custom metrics (see Custom Metrics Resources)
Go to Virtual datacenters → Alarms (see Manage cloud alarms)
Select an Entity (your VM or scaling group), a Metric, and a Metric statistic and enter a Threshold, then save the alarm
