Command port (4 letter words) for monitoring has worked extremely well
for zk. Whatever you do put the command port on a separate port, and
make it a full fledged feature rather than a hack (allow clients to
maintain sessions, allow more complex requests than just a 4letter
word, etc...). Perhaps in today's world you should just go with a REST
interface (easy using jersey) rather than try to implement a
4letterword. json/xml/text for free. easy to integrate with any
monitoring app or adhoc script.
