Net::ZKMon - Perl extension for Apache ZooKeeper Monitoring
===========================================================
About Apache ZooKeeper:
From http://hadoop.apache.org/zookeeper/:
"ZooKeeper is a high-performance coordination service for distributed applications."
It exposes common services - such as naming, configuration management, synchronization, and group services -
in a simple interface so you don't have to write them from scratch.
You can use it off-the-shelf to implement consensus, group management,
leader election, and presence protocols.
Zookeeper exposes 4 letter keywords meant for simple monitoring of the ensemble service.
