JVM WebSphere Liberty Connection Pool Statistics

Applications using Java Connector Architecture (JCA) use pools of connections to JCA providers such as databases or enterprise information systems (EIS). Use these attributes to determine whether the pools are sized properly, or whether response times may be affected by waits for available connections.

ASID Address Space ID (in hex) of the jobname hosting this JVM.

Collector ID Collector ID is the identifier of a JVM collector instance.

Create Count The total number of managed connections that have been created since pool creation.

Connection Handle Count The number of connections that are in use. This number might include multiple connections that are shared from a single managed connection.

Connection Manager ID The connection manager ID.

Destroy Count The total number of managed connections that have been destroyed since pool creation.

Free Connection Count The number of managed connections in the free pool.

InUse Time The average time in seconds that a connection is in use.

InUse Time Max The maximum time in seconds that a connection is in use.

InUse Time Mean The mean time in seconds that a connection is in use.

InUse Time Min The minimum time in seconds that a connection is in use.

InUse Time StdDev The standard deviation of time in seconds that a connection is in use.

Job Name Name of the job or started task hosting this JVM.

Managed Connection Count The total number of managed connections in the free, shared, and unshared pools.

Managed System A collection of the Java Virtual Machines running on the LPAR monitored by IBM® Z OMEGAMON® AI for JVM. Valid values support a 32 byte character string in the form: <collector ID>:<SMF ID>:JVM <collector ID> is the identifier of a JVM collector instance. <SMF ID> is the LPAR identifier.

Process ID USS Process ID of the JVM.

SMF ID SMF ID is the LPAR identifier.

Wait Time The average waiting time in seconds until a connection is granted if a connection is not currently available.

Wait Time Max The maximum waiting time in seconds until a connection is granted if a connection is not currently available.

Wait Time Mean The mean waiting time in seconds until a connection is granted if a connection is not currently available.

Wait Time Min The minimum waiting time in seconds until a connection is granted if a connection is not currently available.

Wait Time StdDev The standard deviation of waiting time in seconds until a connection is granted if a connection is not currently available.
