I use PRIS to generate requisition files. For some reasons it happened that a node was defined like this:

PRIS does not care about if there are two interfaces defined with primary P tag.
But OpenNMS / provisiond does. Unfortunately, it does not tell you.

The logs look like:

An error message like: duplicate entry of snmp-primary

would helped me a lot here. So I think provisiond should print out error messages based on the rule set it has to allow or deny a node definition.
