Returns:

an instance of BoundedRangeStatistic

getTotalBeansCreated

javax.management.j2ee.statistics.CountStatistic getTotalBeansCreated()

Returns the number of Beans created in associated pool so far over time, since the gathering of data started, as a CountStatistic.

Returns:

an instance of CountStatistic

getTotalBeansDestroyed

javax.management.j2ee.statistics.CountStatistic getTotalBeansDestroyed()

Returns the number of Beans destroyed from associated pool so far over time, since the gathering of data started, as a CountStatistic.

Returns:

an instance of CountStatistic

getJmsMaxMessagesLoad
