Hi All, I have a questions about "Additive Inheritance" I have a service that inherits is contact_groups from its host, for this one service I wants to add an additional contact_group(s) but i seem to be having an issue with my understanding of Additive Inheritance an example of the config is define host { ... use generic-host } define service { ... contact_groups +extra_group } so without adding the contact_groups to the service, its contacts are 'contact_group1' and 'contact_group2' When adding the contact_groups to the service (with or without the +), its contact groups are are just 'extra_group' if there is a 'contacts' defined for the host the services: When adding the contact_groups to the service (with or without the +), contacts end up being 'contact1', 'extra_group' Should the + or "Additive Inheritance" not make the service have 'contact_group1' , 'contact_group2' and 'extra_group'? -- <-- <a href="http://23.me.uk/2" target="_blank">http://23.me.uk/2</a> --> <--Time flies like an arrow; fruit flies like a banana. -->
