If you use m4 for your configuration, includes are a breeze with the
'include' command. Actually what most mon+m4 users end up doing is defining
macros for their commonly monitored service parameters which make the end
config file relatively small.
Something like this, for each hostgroup:
SIMPLE_WATCH(`www', `_BOFH_EMAIL_', `http', `https')
where the m4 macros are defined as follows:
define(_BOFH_EMAIL_, `[EMAIL PROTECTED]')dnl
define(_GRAVE_HOURS_, ``wd {Sun-Sat} hr {11pm-6am}'')dnl
define(_NON_GRAVE_HOURS_, ``wd {Sun-Sat} hr {6am-11pm}'')dnl
define(`_SIMPLE_WATCH', `dnl
ifelse(1, $#, ,2, $#, ,3, $#, `SIMPLE_SERVICE($1,`$2',$3)', `dnl
SIMPLE_SERVICE($1,`$2',$3)' `_SIMPLE_WATCH($1, `$2',
shift(shift(shift($@))))')')dnl
dnl ')dnl
dnl #
define(`SIMPLE_WATCH', `dnl
watch $1
service ping
description test service $3 in hostgroup $1
interval 30s
monitor fping.monitor
description ping servers in hostgroup $1
period DAY: _NON_GRAVE_HOURS_

Again, with m4, you can either use file-based includes or even the 'esyscmd'
(assuming GNU m4, which you definitely should be using), which allows you to
insert the output of arbitrary shell commands directly in your m4 output file.

The mailing lists do have some good nuggets, but most are buried. The mailing
list is your best source of info.
