Hobbit doesn't have support for UDP protocols built in, since these 
use mostly binary data - SNMP, DNS, DHCP, NFS and NTP are probably the 
most commonly used UDP-based protocols, and they all carry date in a
binary format, unlike the popular TCP-based protocols.

And unlike TCP, the UDP-based protocols do not have a generic
"handshake" that you can use to check if the service is running.

My best suggestion is to use the tool called "dhcping" to check your 
DHCP servers. It requires some special setup on the DHCP server side,
but once you have it working then creating a custom test script to
run it and report the status to Hobbit should be very simple.
