This release comes with new monitoring support to collect runtime statistics about performance relevant behavior and state. Statistics are published through Java Management Extensions (JMX). You can now use jconsole or a similar JMX monitoring tool to view graphed information about queries, the free space manager, the object reference system, IO, and networking. Since this is still a work in progress, you may expect to see changes in the API and the list of actual statistics supported
