My thoughts were that this proxy server would do the pulling,
effectively mimicking the Nagios server,
 then push the data on to the Hobbit server in a similar way to your
bbproxy program. I had planned on
 cheating for the initial version. For those checks that use the NRPE
plug-in the proxy
 would simply run the check_nrpe program passing it the parameters
needed to execute the remote plug-in. It
 would then parse the return data and massage it into Hobbit-speak.

I took a look at the weekend but came up against a wall trying to
extract the relevant code from
 bbproxy. I think the issue I was having was that bbproxy is heavily
written to merge multiple packets from
 the client (combining) and send them on to the Hobbit server in one go.
I just needed something that told
 me what the format of a bbproxy data packet looked like and how to send
it to the main server.

Ah well, I will see if I can get access to a production Nagios server
(the one I am supposed to be replacing)
 and see what info I can get from that.
