Constructor Detail

ExecuteQueueThreadsVital

public ExecuteQueueThreadsVital(java.lang.String vitalKey,
                                VitalSignProperties properties)

Creates the vital sign. This method must pass-through to the super-class so the vital sign can be auto-loaded.

Method Detail

hasChildInstances

public boolean hasChildInstances()

This vital sign has child instances to collect measurements.

Overrides:

hasChildInstances in class VitalSign

See Also:

VitalSign.hasChildInstances()

getQueueName

public java.lang.String getQueueName()

Returns the name of the thread pool queue. Queue name is a unique key and can therefore be used as the child vital key.

getExecuteQueueRuntimeMBean

public weblogic.management.runtime.ExecuteQueueRuntimeMBean getExecuteQueueRuntimeMBean()

Retrieves the runtime MBean for a named execute queue

getCurrentMeasurement

protected AbstractVitalMeasurement getCurrentMeasurement()

Takes a measurement of the vital sign at the current moment and returns it to the caller. This method should be implemented by subclasses that are automatically called by the vitals manager on a periodic basis. The default implementation in this superclass is to return null, leaving the implementation to a subclass.

Overrides:

getCurrentMeasurement in class VitalSign

Returns:

the current measurement for this vital sign or null if no implementation

basicGetMaximumMeasurement

public AbstractVitalMeasurement basicGetMaximumMeasurement()

Returns the maximum theoritical value of the vital sign.

Overrides:

basicGetMaximumMeasurement in class VitalSign

Returns:

the current measurement for this vital sign or null if no implementation

refreshChildInstances

public void refreshChildInstances()

Looks at all the registered execute queues and activates children for each one currently applicable.

Overrides:

refreshChildInstances in class VitalSign

VitalSign.refreshChildInstances()
