public interface: Statistics [javadoc | source]

All Known Implementing Classes:
    StatisticsService, StatisticsServiceMBean, StatisticsImpl

Statistics for a particular SessionFactory. Beware of milliseconds metrics, they are depdendent of the JVM precision: you may then encounter a 10 ms approximation dending on you OS platform. Please refer to the JVM documentation for more information.
