Nagios Plugin to monitor Zookeeper

Checks:

1. ruok – checks to see if ZooKeeper reports itself as ok
2. isro – checks to see if ZooKeeper is still writable
3. mode – checks to see if ZooKeeper is in the proper mode (leader/follower) vs standalone
4. avg latency – the average latency reported by ZooKeeper is within the thresholds given. Optional
5. stats – full stats breakdown
6. also reports ZooKeeper version

-w –warning Warning threshold or ran:ge (inclusive) for avg latency
