I am sure Nagios has its benefits, as does Xymon, we're just more likely
to consider Xymon first.

You are asking about having a Nagios server talk to a Hobbit client,
yes? In this case what you are asking for is certainly possible, just
not simple.

Nagios is not a client-server application. It works by the server
initiating tests on the clients and reading the response. Xymon works by
listening on a port for data sent from the client, the client initiates
its own tests. With a Xymon server and a Nagios client it's fairly easy
(it must be since I have done it) to have a proxy server that initiates
the Nagios test on the client and report back to the Xymon server.

However, with a Nagios and a Xymon client it's more difficult. The
client would run when it was configured to and try to send data back to
the Nagios server, which isn't ready to accept data form the client
since it hasn't initiated a test.

If you really want to do this you are going to have to write (or get
your student to write) a proxy server that listens on port 1984 and
stores any client data from the Xymon client on disk. Then, when the
Nagios server initiates a test another program reads the data from the
disk and sends back the corresponding information.

How you tie up the data sent from the client to the data requested by
the server is up to you and your student to figure out.
