Info

For a scaling group, an alarm in the base workload will receive input from the metrics of all machines in the scaling group. This means the base workload and/or the clone machines. So an alarm for a scaling group can activate, even if the base workload is not deployed.

Before you begin:

    • Click Save

    , and alarms for built-in metrics for VMs that you can access through the infrastructure path of their providers.

    You can enable metrics automatically for all VMs by TODO

    To create an alarm:

    1. Edit a virtual machine
      1. Check that you are retrieving metrics
        • If you are not retrieving metrics, you may create an alarm but it will not be triggered
