Interface ConnectionPoolStats

All Superinterfaces:

Stats

All Known Subinterfaces:

ConnectionFactoryStats, ConnectorConnectionPoolStats, JDBCConnectionPoolStats

public interface ConnectionPoolStats
extends Stats

A Stats interface to represent the statistical data exposed by a Connection Pool. All the Connection Pool implementations should expose statistical data by implementing this interface.

Method Summary

Methods

Modifier and Type	Method and Description
CountStatistic	getAverageConnWaitTime() Indicates the average wait time of connections, for successful connection request attempts to the connector connection pool
RangeStatistic	getConnRequestWaitTime() Indicates the longest, shortest wait times of connection requests.
CountStatistic	getNumConnAcquired() indicates the number of logical EIS/JDBC connections that were acquired from the pool, since the last reset
CountStatistic	getNumConnCreated() indicates the number of physical EIS/JDBC connections that were created, since the last reset
CountStatistic	getNumConnDestroyed() indicates the number of physical EIS/JDBC connections that were destroyed , since the last reset
CountStatistic	getNumConnFailedValidation() represents the number of connections that failed validation
RangeStatistic	getNumConnFree() Indicates the number of free connections in the pool in addition to their high and low watermarks.
CountStatistic	getNumConnNotSuccessfullyMatched() Indicates the number of connections that were rejected by the Managed Connection Factory during matching.
CountStatistic	getNumConnReleased() indicates the number of logical EIS/JDBC connections that were released to the pool, since the last reset
CountStatistic	getNumConnSuccessfullyMatched() Indicates the number of connections that were successfully matched by the Managed Connection Factory.
CountStatistic	getNumConnTimedOut() represents the number of connection requests that timed out
RangeStatistic	getNumConnUsed() Statistic to represent the Connection Usage In addition to information about the number of connections being used currently, this also contains information about the Maximum number of connections that were used(High Watermark)
CountStatistic	getNumPotentialConnLeak() Indicates the number of potential connection leaks
CountStatistic	getWaitQueueLength() Indicates the number of connection requests in the queue waiting to be serviced
