Based on KATTA-82.
Some initial thoughts for discussion:
- things we want to monitor ?
- we have:
- cpu, memory, garbage collection
- we might want ?:
- disc-io/allocation (support multiple discs first)
- shard distribution, query distribution, cluster balance (have this partly in zk)
- how do we publish those ?
- currently a IMonitor publishes to zk
- do we want to publish via jmx ?
- publish to ganglia ?
- we might extend our IMonitor solution to run multiple IMonitors at the same time

Improvement

Major
improve katta's monitoring abilities
This is huge progress.
+1 for ganglia. It allows new users to see monitoring results easily.
JMX is nice as well, but the portmapper issues make it hard to export outside a firewall.
