Hobbit can monitor rpc services, see bb-hosts(5). But, this only checks that 
the rpc program is registered on the host.

Sure, so you could write a trivial extension script for the server that does 
this.

This could also be an extension script on any hobbit client (and, it would 
then also be able to test for being able to write to certain NFS shares).

You could also use a "file" monitor on any of your NFS clients.
