You can register the following listeners:

ConnectionListenerIF

Listen to the activity of each connection. When it is born (when a new Connection is made), everytime it executes, when it fails (and what the command was that it failed on), and when it dies (when we finally throw the Connection away).

StateListenerIF

Monitors the state of the pool so you can see whether it is quiet, busy, overloaded, or down.

ConfigurationListenerIF

Listens to any changes made to the definition giving you the opportunity to persist a definition.

StatisticsListenerIF

Listen for new statistics as they are produced.
