I'm not aware of a dedicated utility. However, the KDC is basically a
stateless UDP service, so recording a live transaction and replaying an
input packet is expected to yield some sort of response packet. Doing
this periodically allows for a very primitive "liveness check" which can
be used in some monitoring setups. Of course, if one wants to monitor
that the KDC is actually functioning properly and not just spewing error
packets, more effort is required.
