Method Detail

startMeter

public boolean startMeter(long interval,
                          boolean dropPriorReading)

Description copied from class: AggregatedEnergyMeter

Dispatches start meter calls to all supervised meters. If even one of them fails, it immediately terminates those meters that were started before the failure.

Overrides:

startMeter in class AggregatedEnergyMeter

Parameters:

interval - The meter refresh frequency.

dropPriorReading -

False: the totalConsumption values will accumulate from a previous metering session True: the totalconsumption values will start from 0 after the completion of this function.

Returns:

• False: if a metering session is already underway
• True: if the metering session was successfully initiated

stopMeter

public void stopMeter()

Description copied from class: AggregatedEnergyMeter

Dispatches stop meter calls to all supervised meters

Overrides:

stopMeter in class AggregatedEnergyMeter

capacityChanged

public void capacityChanged(ResourceConstraints newCapacity,
                            List<ResourceConstraints> affectedCapacity)

Specified by:

capacityChanged in interface VMManager.CapacityChangeEvent<ResourceConstraints>

getObserved

public PhysicalMachine getObserved()
