org.hibernate.jmx
Class StatisticsService

java.lang.Object
  org.hibernate.jmx.StatisticsService

All Implemented Interfaces:

Statistics, StatisticsServiceMBean

---

public class StatisticsService

extends Object

implements StatisticsServiceMBean

JMX service for Hibernate statistics

Register this MBean in your JMX server for a specific session factory

 //build the ObjectName you want
 Hashtable tb = new Hashtable();
 tb.put("type", "statistics");
 tb.put("sessionFactory", "myFinancialApp");
 ObjectName on = new ObjectName("hibernate", tb);
 StatisticsService stats = new StatisticsService();
 stats.setSessionFactory(sessionFactory);
 server.registerMBean(stats, on);
 

And call the MBean the way you want

Register this MBean in your JMX server with no specific session factory

 //build the ObjectName you want
 Hashtable tb = new Hashtable();
 tb.put("type", "statistics");
 tb.put("sessionFactory", "myFinancialApp");
 ObjectName on = new ObjectName("hibernate", tb);
 StatisticsService stats = new StatisticsService();
 server.registerMBean(stats, on);
 

And call the MBean by providing the SessionFactoryJNDIName first. Then the session factory will be retrieved from JNDI and the statistics loaded.
