Liberty profile: ConnectionPool monitoring

You can use the ConnectionPool MXBean for ConnectionPool monitoring of the Liberty profile.

Performance data of ConnectionPool for each data source is made available.

Each data source has a ConnectionPool MXBean associated with it, and there is one MXBean for every data source.

The ObjectName for identifying each ConnectionPool MXBean is:
WebSphere:type=ConnectionPool,name=*
For example:
WebSphere:type=ConnectionPool,name=jdbc/TradeDataSource

The ConnectionPool MXBean is responsible for reporting ConnectionPool Stats for a single data source. The following counter attributes are available for the ConnectionPool MXBean after monitoring is enabled:

CreateCount
The total number of connections created.
DestroyCount
The total number of connections destroyed.
ManagedConnectionCount
The number of ManagedConnection objects that are in use.
WaitTime
The average waiting time in milliseconds until a connection is granted.
ConnectionHandleCount
The number of Connection objects that are in use.
FreeConnectionCount
The number of free connections in the pool.
