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.

Control and scaling concepts


ConceptDescription
MetricA 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
AlarmAn 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
AlertAn 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 planA sequence of actions to perform on entities on the platform, such as VMs or scaling groups. An action plan is run by a trigger.
TriggerA trigger is an alert or a schedule that will run the action plan, for example, during times of increased demand. 
Scaling groupFor 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 scalingVertical scaling means scaling up, adding more resources to an existing VM, for example, boosting your CPU and or RAM capacity.
Horizontal scalingHorizontal scaling means scaling out, deploying more VMs when you need more resources. 





Create alerts to notify users and trigger automation

The platform's Alerts feature enables you to track and act upon changes in your cloud environment. To configure Alerts do these steps:

  1. Go to Virtual datacenters → Virtual Appliances → Virtual machines. 
  2. Create and configure your VMs. See Manage Virtual Machines
    1. Remember to go to Monitoring and fetch metrics. See VM monitoring and metrics
  3. Go to Virtual Appliances → Monitoring and check that the platform is retrieving metrics. You may have to wait a few minutes
  4. Create alarms for built-in metrics, scaling group metrics, and custom metrics as required

    1. To create alarms, go to Virtual datacenters → select virtual datacenter → Alarms (see Manage cloud alarms) or Infrastructure → select datacenter → Alarms (see Infrastructure Alarms).

    2. Select an entity, a metric, and a metric statistic and enter a threshold

    3. Save the alarm

  5. Create alerts to notify users

    To create an alert:

    1. Go to ControlAlerts
    2. Click the + add button
    3. Enter the alert details and assign alarms as described below

    4. Click Save


    Field

    Description

    Name

    Name of the alert. The name can contain up to 128 characters

    DescriptionDescribe the alert
    MutedSelect this checkbox to disable action when the alert is activated
    EmailList 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. 


    • You can also use alerts to trigger scaling, see Cloud bursting. 




Configure automation with action plans

Cloud bursting is automatically deploying new resources in any part of your hybrid cloud environment to meet a peak in demand for resources. To prepare cloud bursting, create an application with metrics and create a matching application in another provider with an action plan that will scale when triggered by VM metrics or on schedule.

To configure cloud bursting do these steps:

  1. Create your application: deploy VMs with monitoring of critical values
  2. Create a matching appliance in another cloud. Deploy VMs with replication and use minimal hardware profiles
  3. Create alarms for your critical values ofVM metrics, scaling group metrics, or custom metrics (see Custom Metrics Resources)

    1. Go to Virtual datacentersAlarms (see Manage cloud alarms)

    2. Select an Entity (your VM or scaling group), a Metric, and a Metric statistic and enter a Threshold, then save the alarm

    We recommend that you create alarms for when you will require more resources (the high threshold), and for when these resources can be retired (the low threshold).
  4. Create alerts to notify users and to trigger scaling
    1. Go to Control → Alerts (see Manage Alerts)
  5. Create action plans for automation
    1. Go to Control → Action plans (see Manage Action Plans) 
    2. Select a VM or scaling group
    3. Create Actions, for example, increase the hardware profile of a VM, or use scaling actions to add more VMs for your application.
    4. Add an Alert to trigger the action plan or create a Schedule to run it. If you use a schedule, the alarms and alerts are optional but recommended because they can help you control your cloud resources.
