programmatically determining whether any zones frozen?

[jeffreyp]

greetings,

is there a way to programmatically determine if there are any zones
frozen?  if so, any way to determine the specific zone(s)?

what i'm wanting to do is write a monitoring script to sound an alert if
there are any zones that have been frozen for more then x minutes.

rndc doesn't provide that info and i haven't found anything else to
accomplish the task.

thanks for the help.
