Distributed monitoring and dependencies

[Henti Smith]

Good day all.

I've taken over ownership of a very hacked and mutilated nagios
installation in house, and I'm busy building a migration plan and
designing the new nagios instance.

I have some questions which the documentation is not making apparent,
likely due to my lack of understanding nagios, not the documentation.

We have 3 physical locations which will be monitored, which will
likely increase, and I'm looking at a distributed monitoring setup as
described in the documentation here :

http://nagios.sourceforge.net/docs/3_0/distributed.html

Now the documentation mentions :

"The purpose of the central server is to simply listen for service
check results from one or more distributed servers. Even though
services are occassionally actively checked from the central server,
the active checks are only performed in dire circumstances, so lets
just say that the central server only accepts passive check for now"

We are also looking at using dependencies between hosts and services
across all locations, which according to the documentation and my
understanding of it, might be a problem.

"Execution dependencies are used to restrict when active checks of a
service can be performed. Passive checks are not restricted by
execution dependencies"

Unfortunately the check scheduling logic link is still in TODO status,
so I cannot explore further.

Is my understanding correct ?

If not, can you use distributed monitoring and host and service dependencies ?

As a final question. I'd like to be able to monitor a single host from
the different locations to be able to identify links going down using
the above configuration. Would I have to configure the host 3  times
for each nagios server or is there a different way.

Regards
Henti
