In Infrastructure view you can create alarms for custom metrics. You can also create alarms for built-in metrics for VMs that you can access through the infrastructure path of their providers.

To create custom metrics for infrastructure elements, including datacenters, racks, and physical machines, use the API. To automatically fetch metrics for all VMs, after you configure and enable monitoring for the platform, set the Enable virtual machine monitoring by default property to true in Configuration view.

To create an alarm:

1. Go to Infrastructure → Alarms and click the + button
2. Enter the alarm details as described here
3. Click Save

The platform will create the alarm for the metric. If you would like the platform to notify you when this alarm activates, create an Alert for it in the Control view. You can create multiple alerts that include multiple alarms.

To create alarms for virtual appliances and virtual datacenters go to Virtual datacenters → Alarms. See Manage cloud alarms v44

Edit an alarm

When you edit an alarm, you cannot modify the metric or the entity.

When you edit an alarm, there is an extra field, "Active", that shows if the alarm is activated or not.

Delete an alarm

You can delete any alarm at any time, even if it is part of one or more alerts.

The platform will not warn you that the alarm is used in an alert. However, you can check this in Control view.

After you delete an alarm, you cannot recover it.

If you delete a VM, the platform will delete any alarms associated with its metrics.
