Thanks for the reply, but writing a function (I took a look at [DSL: Flatten a nested dictionary with a function for apply for rules](https://community.icinga.com/t/dsl-flatten-a-nested-dictionary-with-a-function-for-apply-for-rules/1330)) would complicate things rather than making it easier.  
Unless you have a straightforward example of such a function at hand? 😉

Oh and I can’t use “if” inside the `apply` rule because it is managed by puppet-icinga2.
