Hello, Maybe have a look at our nagios module: https://github.com/camptocamp/puppet-nagios
Your problem is that resources with same name are exported from multiple hosts,
and that make puppet crash with duplicated definition (as it's exported
resources, the error message is different ;) ).
You should name your nagios resources with the fqdn embedded so that it will be
really unique across the DB.
Cheers,
C.
