Hi Prabhjot, Short answer: yes I used to think ZK was so super stable that it was one of those things that don't require any management, but on a few occasions I witnessed complex distributed applications nearly fall apart because of issues with ZK. We use our own SPM for ZooKeeper to monitor all our ZK nodes. I'm not a ZK expert, but metrics like Request Latency, Watch Count, Outstanding Requests seem important.
