ZooKeeper

2181

ZooKeeper Port

Note:

IT Analytics uses standalone installation of single-node Apache ZooKeeper server. For secure communications, ZooKeeper single-node cluster must be protected from external traffic using network security such as firewall. This is remediated by ensuring that the ZooKeeper port (2181) is only accessible on the localhost where IT Analytics Portal/Data Collector is installed (that includes Apache ZooKeeper).

+ indicates an Admin port
