public class ExampleTakeCPUDemandProbe
extends BasicEventProbe<ASimpleActiveResource,Double,javax.measure.quantity.Duration>
implements Observer

Measures a resource demand metric (in SI.SECOND) by taking the demand emitted from an active resource (event source), e.g., a CPU. This class uses ASimpleActiveResource as an example active resource.

Constructor Detail

ExampleTakeCPUDemandProbe

public ExampleTakeCPUDemandProbe(ASimpleActiveResource activeResource)

Default constructor.

Parameters:

activeResource - The event source is an active resource (e.g., a CPU), thus, able to emit demand events.

Method Detail
