Name Key Description Granularity Type Level Num managed connections j2cModule.numManagedConnections Number of ManagedConnection objects in use Per connection factory CountStatistic Low Num connection handles j2cModule.numConnectionHandles Number of connections that are associated with ManagedConnections (physical connections) in this pool Per connection factory CountStatistic Low Num Connections Created j2cModule.numManagedConnectionsCreated Total number of managed connections created Per connection factory CountStatistic Low Num Connections Destroyed j2cModule.numManagedConnectionsDestroyed Total number of managed connections destroyed Per connection factory CountStatistic Low Num Connections Allocated j2cModule.numManagedConnectionsAllocated Total number of times a managed connection is allocated to a client (the total is maintained across the pool, not per connection). Per connection factory CountStatistic Low Num Connections Freed j2cModule.numManagedConnectionsReleased Total number of times a managed connection is released back to the pool (the total is maintained across the pool, not per connection). Per connection factory CountStatistic Low Num Faults j2cModule.faults Number of faults, such as timeouts, in connection pool Per connection factory CountStatistic Low Free Pool Size j2cModule.freePoolSize Number of free connections in the pool Per connection factory BoundedRangeStatistic High Pool Size j2cModule.poolSize Average number of managed connections in the pool. Per connection factory BoundedRangeStatistic High Concurrent Waiters j2cModule.concurrentWaiters Average number of threads concurrently waiting for a connection Per connection factory RangeStatistic High Percent Used j2cModule.percentUsed Average percent of the pool that is in use Per connection factory RangeStatistic High Percent Maxed j2cModule.percentMaxed Average percent of the time that all connections are in use Per connection factory RangeStatistic High Avg Wait Time j2cModule.avgWait Average waiting time in milliseconds until a connection is granted Per connection factory TimeStatistic Medium Avg Use Time j2cModule.useTime Average time in milliseconds that connections are in use Per connection factory TimeStatistic Medium
