be able to configure statistics enablement
------------------------------------------

                 Key: HHH-3593
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3593
             Project: Hibernate Core
          Issue Type: Improvement
          Components: core
            Reporter: John Mazzitelli
            Priority: Minor


Right now, in order to enable Hibernate to collect and emit statistics to monitoring tools, your application has to manually execute code similar to the following:

   StatisticsService mBean = new StatisticsService();
   SessionFactory sessionFactory = ...get hibernate session factory...
   mBean.setSessionFactory(sessionFactory);
   ObjectName objectName = new ObjectName("Hibernate:application=MY_APP_NAME,type=statistics");
   MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
   mbs.registerMBean(mBean, objectName);
   sessionFactory.getStatistics().setStatisticsEnabled(true);

It would be nice if this was configurable, so a user of Hibernate doesn't need to write this code.

For example:

hibernate.statistics.enabled=true
hibernate.statistics.objectname=Hibernate:application=MY_APP_NAME,type=statistics
hibernate.statistics.mbeanserver=*platform*

This would turn on Hibernate statistics and tell it to register the Statistics MBean in the JVM's platform MBean Server (ManagementFactory.getPlatformMBeanServer). Of course, *platform* would only be valid on Java5 or higher VMs. Note that hibernate will need to allow the object name to be configurable as well.

Or...

hibernate.statistics.enabled=true
hibernate.statistics.objectname=Hibernate:application=MY_APP_NAME,type=statistics
hibernate.statistics.mbeanserver=my_mbs_name

This tells Hibernate to register the MBean in the named MBeanServer where the "my_mbs_name" is the default domain name of the MBeanServer you want (if it doesn't exist, Hibernate should create the MBeanServer with the named default domain).

In fact, I had the Remoting project do something similar, so you can see code that gets the MBeanServer using these two ways by looking at the .patch attached to: https://jira.jboss.org/jira/browse/JBREM-746 and its related fix.
