The rule is: Put all of your tags on one of these definitions, and
ONLY a "noconn" on the others.
So using your example:
group-only bbd|bbgen|bbtest|hobbitd|rsync Hobbit Monitoring
Server 123.123.123.123 123.123.123.123 # noconn
page game-servers Main Game Server Boxes. group-except
bbd|bbgen|bbtest|hobbitd|rsync 123.123.123.123 123.123.123.123 #
ftp !telnet !smtp ssh ntp prefer badconn:1:2:4 bbd rsync
There's no link between the "group-only" or "group-except"
definitions, and where you have the network tests defined, so even
though it might seem a bit odd with "group-except bbd|rsync" and then
those two tests listed on the first host-entry, it will work the way
you want it to. Because the tool the runs the network tests ignores
all of the page, subpage, group* definitions; and the tool that
builds the webpages ignores how all of the network tests were defined
(it just looks at what status columns are available).
