4lw and jmx should expose the size of the datadir/datalogdir
------------------------------------------------------------
Key: ZOOKEEPER-1423
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1423
Project: ZooKeeper
Issue Type: Improvement
Components: jmx
Reporter: Patrick Hunt
There are no metrics currently available on the size of the datadir/datalogdir.
These grow w/o bound unless the cleanup script is run. It would be good to
expose these metrics through jmx/4lw such that monitoring can be done on the
size. Would key ppl in on whether cleanup was actually running. In particular
this could be monitored/alerted on by third party systems (nagios, ganglia and
the like).
