Advances servicedependency configuration

[Andy Shellam]

Hi,

I'm sure this has been implemented in Nagios 3.  I wrote an on-line 
application that generated service dependencies for individual 
hosts/services in a group in Nagios 2, and I'm sure I read that was now 
no longer an issue in v3.

 From the manual - 
http://nagios.sourceforge.net/docs/3_0/objecttricks.html#same_host_dependency:

"If you want to create service dependencies for multiple services that 
are dependent on services on the same host, leave the 
/dependent_host_name/ and /dependent_hostgroup_name/ directives empty."

Is this what you were trying to achieve?
