```
public class TakeScheduledResourceStateProbe
extends org.palladiosimulator.probeframework.probes.BasicObjectStateProbe<AbstractScheduledResource,Long,javax.measure.quantity.Dimensionless>
```
Measures a CPU state metric (dimensionless) by requesting the queue length from the scheduled CPU resource (observed state object). Because scheduled resources can have many instances (e.g., a CPU can have many cores), a pointer to the concrete instance is used additionally.

public TakeScheduledResourceStateProbe(AbstractScheduledResource scheduledResource,
                                       int instance)
```
    Default constructor.
    
    Parameters:
    
    scheduledResource - The observer object is a scheduled resource, thus, allowing to request its queue length.
    
    instance - Pointer to the concrete instance of the scheduled resource, e.g., CPU 0.
