Curator is excellent at this. Additionally, zk_watcher is a simple way of doing this as well.
(for what its worth, we do almost exactly this at Nextdoor... every server we have runs this daemon, and they register various bits of data about themselves in a Zookeeper path. We then leverage this path with other tools for getting full server-lists.)
