Enterprise Java Bean counters: WAS ND

Enterprise Java Bean counters

Counters for this category report load values, response times, and life cycle activities for enterprise Java beans.

Note: With the instrumentation level set to anything other than MAX, the values may be less accurate for TimeStatistics and CountStatistics (and in the case of CountStatistics, such as numConnectionHandles, can even be negative). This is due to counters not being synchronized. Synchronizing counters is very expensive in terms of resources, so it is only done when the instrumentation level is set to MAX.
