Package com.sun.enterprise.resource.pool.monitor

Class ConnectionPoolStatsProviderBootstrap

java.lang.Object

com.sun.enterprise.resource.pool.monitor.ConnectionPoolStatsProviderBootstrap

All Implemented Interfaces:

PoolLifeCycle, org.glassfish.hk2.api.PostConstruct

@Service
@Singleton
public class ConnectionPoolStatsProviderBootstrap
extends Object
implements org.glassfish.hk2.api.PostConstruct, PoolLifeCycle

Bootstrap operations of stats provider objects are done by this class. Registering of provider to the StatsProviderManager, adding pools to the PoolLifeCycle listeners are done during the bootstrap. Depending on the lifecycle of the pool - creation/destroy, the listeners are added or removed and providers registered/unregistered. This is an implementation of PoolLifeCycle. All pool creation or destroy events are got and based on the type, provider is registered for a pool if pool is created or provider is unregistered if pool is destroyed. Monitoring levels when changed from HIGH-> OFF or OFF->HIGH are taken care and appropriate monitoring levels are set.

ConnectionPoolStatsProviderBootstrap

public ConnectionPoolStatsProviderBootstrap()

Method Detail

addToPoolEmitters

public void addToPoolEmitters(PoolInfo poolInfo,
                              ConnectionPoolEmitterImpl emitter)

registerProvider

public void registerProvider()

All Jdbc Connection pools are added to the pool life cycle listener so as to listen to creation/destroy events. If the JdbcPoolTree is not built, by registering to the StatsProviderManager, its is done here.

postConstruct

public void postConstruct()

Specified by:

postConstruct in interface org.glassfish.hk2.api.PostConstruct

registerPool

public PoolLifeCycleListenerRegistry registerPool(PoolInfo poolInfo,
                                                  ConnectionPoolProbeProvider poolProvider)

Registers the pool lifecycle listener for this pool by creating a new ConnectionPoolEmitterImpl object for this pool.

Parameters:

poolInfo -

Returns:

registry of pool lifecycle listeners

registerPool

public ConnectionPoolAppProbeProvider registerPool(PoolInfo poolInfo,
                                                   String appName)

getResources

public Resources getResources()

getProbeProviderUtil

public ConnectionPoolProbeProviderUtil getProbeProviderUtil()

unRegisterPool

public void unRegisterPool()

postUnregisterPool

public void postUnregisterPool(PoolInfo poolInfo)

unregisterPoolAppProviders

public void unregisterPoolAppProviders(PoolInfo poolInfo)

getEnabledValue

public boolean getEnabledValue(String strEnabled)

Find if the monitoring is enabled based on the monitoring level : strEnabled

Parameters:

strEnabled -

Returns:

poolCreated

public void poolCreated(PoolInfo poolInfo)

When a pool is created (or initialized) the pool should be registered to the StatsProviderManager. Also, the pool lifecycle listener needs to be registered for this pool to track events on change of any monitoring attributes.

Specified by:

poolCreated in interface PoolLifeCycle

Parameters:

poolInfo -

poolDestroyed

public void poolDestroyed(PoolInfo poolInfo)

When a pool is destroyed, the pool should be unregistered from the StatsProviderManager. Also, the pool's lifecycle listener should be unregistered.

Specified by:

poolDestroyed in interface PoolLifeCycle

Parameters:

poolInfo -
