A virtual alarm is a special type of alarm that allows you to derive a new result from the status(es) of one or more existing alarms.

Any alarms in iControl — including other virtual alarms — can be combined together to form a new, higher-level virtual alarm. You cannot, however, create a virtual alarm that includes itself as a sub-alarm, since this creates a cyclical dependency. iControl automatically checks for this dependency, and will alert you of any potential problems.

Since a virtual alarm can be composed of virtual alarms other than itself, there can be many levels of virtual alarms within a particular virtual alarm. At this time there is no limit to the number of levels that a virtual alarm can have.
