3.6. Hibernate - Statistics Service
Overview
| Description: | Statistics for Hibernate |
| Singleton: | no |
| Plugin: | Hibernate |
Note
In order to monitor Hibernate statistics via JON, the Hibernate Session Manager MBean must be deployed to an object name of the format {{_"Hibernate:application=%application%,type=statistics"_}}, and statistics must be enabled. Some example code is provided below to register the Hibernate Session MBean within an EJB3 application. {code} public static void enableHibernateStatistics(EntityManager entityManager) { try { StatisticsService mBean = new StatisticsService(); SessionFactory sessionFactory = getHibernateSession(entityManager).getSessionFactory(); mBean.setSessionFactory(sessionFactory); ObjectName objectName = new ObjectName(HIBERNATE_STATISTICS_MBEAN_OBJECTNAME); MBeanServer jbossMBeanServer = getJBossMBeanServer(); jbossMBeanServer.registerMBean(mBean, objectName); sessionFactory.getStatistics().setStatisticsEnabled(true); } catch (InstanceAlreadyExistsException iaee) { LOG.info("Duplicate MBean registration ignored: " + HIBERNATE_STATISTICS_MBEAN_OBJECTNAME); } catch (Exception e) { LOG.warn("Couldn't register Hibernate statistics MBean.", e); } } private static Session getHibernateSession(EntityManager entityManager) { Session session; if (entityManager.getDelegate() instanceof EntityManagerImpl) { EntityManagerImpl entityManagerImpl = (EntityManagerImpl) entityManager.getDelegate(); session = entityManagerImpl.getSession(); } else { session = (Session) entityManager.getDelegate(); } return session; } private static MBeanServer getJBossMBeanServer() { List<MBeanServer> servers = MBeanServerFactory.findMBeanServer(null); MBeanServer jbossServer = null; for (MBeanServer server : servers) { if ("jboss".equals(server.getDefaultDomain())) { jbossServer = server; } } if (jbossServer == null) { jbossServer = ManagementFactory.getPlatformMBeanServer(); } return jbossServer; } {code} See also [Publishing statistics through JMX|http://hibernate.org/216.html] and [Enabling Hibernate statistics|http://www.redhat.com/docs/manuals/jboss/jboss-eap-4.3/doc/hibernate/Hibernate_Reference_Guide/Optional_configuration_properties-Hibernate_statistics.html]
