I am in a very similar situation and one of the people that expressed
interest in the "netsock" solution, altho my interest was also of a
different nature , you can see my old post here for some details if

I'd like to add another option to the list:
5. Create a RESTful webservice to expose stored data
This would allow to develop checks that could be more complicated than
just looking at the last value.
This also plugs into this thread:
"Shouldnt collectd also provide an interface to the data?"
which was aiming at pretty much the same thing and got similar
pointers to netcmd.
In my mind we want both, but for different reasons, and as far as
nagios is concerned imho creating a RESTful webservice is the right
choice in the way that different kinds of consumers can be written
that could heavily benefit from having access to the entire dataset.
Not to mention that if you run a large infrastructure you got to
appreciate the benefits of flexibility and security (with ssl) of
I'll be trying to find some time to look at netcmd for caching next
month so I renew Florian's invitation in keeping the dev cycle short
and post updates to the list.
