I have setup the basic Centralized/Distributed model. I have a Distributed Nagios install doing the services checks, that in turn send them via NSCA to my Central Nagios Server. To make it clear; when the Nagios documentation says:
" The central server must have service definitions for all services that are being monitored by all the
distributed servers. Nagios will ignore passive check results if they do not correspond to a service
that has been defined."
I assume this means that the Central server needs mirror copies (withholding the active service check option) of contacts,contact groups, hosts, host groups and of course services (with the passive check set to 1) from each distributed server to be able to receive, process and notify on passive checks.
Any insight would be much appreciated,
