enhancement request: implicit this host servicedependency definition option

[Paul Fitzpatrick]

As a template object, it would be very useful to have the capability within
a servicedependency definition to be able to express without explicitly
listing host_name(s) the following dependency relationship:

make service A depend on service B on only self-same host,  of hostgroup X

It might look something like this:

define servicedependency {

   service_description                      service B
   dependent_service_description     service A
   dependent_hostgroup                  hostgroup X
   host_name                                 SELF

}

Currently it appears that the only way to do this is to list explicitly all
of the hostnames where this type of service dependency is desired (leaving
off the dependent_hostgroup line).  Having the SELF keyword (or some
equivalent mechanism) would greatly simplify the use of a template object to
define this kind of dependency.

I have written a perl-script to expand the members of the
dependent_hostgroup using the objects.cache file as the source
for the hostgroup members to populate this type of servicedependency
definition with the relevant host_name(s). It has the obvious deficiency
that it depends on an exiting running configuration, and will not include
newly-added hosts from a config that's been updated since the last restart.

A former collegue has written a nagios patch to do just this for an old
release of nagios (2.01a).  We have moved to version 3.0, so the patch is no
longer useable.

I can supply my script and/or the 2.01a patch if there is interest.
