public class TakeScheduledResourceUtilization
extends org.palladiosimulator.probeframework.probes.BasicObjectStateProbe<AbstractScheduledResource,Double,javax.measure.quantity.Dimensionless>

Measures the CPU utilization (dimensionless) by requesting the queue length from the scheduled CPU resource (observed state object) for all cores normalized by the number of cores. If one core is busy with 2 processes and another core is idle for a 2 core system then the utilization is 50%.

Constructor Detail

TakeScheduledResourceUtilization

public TakeScheduledResourceUtilization(AbstractScheduledResource scheduledResource)

Default constructor.

Parameters:

scheduledResource - The observer object is a scheduled resource, thus, allowing to request its queue length.

Method Detail

getBasicMeasure

protected javax.measure.Measure<Double,javax.measure.quantity.Dimensionless> getBasicMeasure(org.palladiosimulator.probeframework.measurement.RequestContext measurementContext)

Measures the queue length from the scheduled resources (observed state object).

Specified by:

getBasicMeasure in class org.palladiosimulator.probeframework.probes.BasicTriggeredProbe<Double,javax.measure.quantity.Dimensionless>
