To make sure I have your problem correctly...

Your DNS server can only listen on one IP, the VIP. 
Mon running on the director can't query processes bound
to the VIP on the realservers, so it usually queries 
the process bound to the RIP, and hopefully this is an indication
of the state of the process bound to the VIP.

Can you instead have mon on the director [rs]sh to the RIP and
run dns.monitor on the realserver?
