Question about Page= in hobbit-alerts

[Lowery, Michael]

Running 4.02

I have a page defined as mon1 in bb-hosts, there are no hosts defined on
the page, but there are 2 subpages defined, mon1-a and mon1-b.  

I setup an alert which does not work, that looks like:

PAGE=mon1 SERVICE=* DURATION>10
MAIL myaddress at mydomain.com

Do I have to define this for each subpage to get it to work?  If so, how
do I format the PAGE= ?

Thanks,
Michael
