public class ExampleTakePassiveResourceStateProbe
extends BasicObjectStateProbe<ASimplePassiveResource,Long,javax.measure.quantity.Dimensionless>

Measures a passive resource state metric (dimensionless) by taking the number of free resources within a passive resource (observed state object), e.g., a connection pool. This class uses ASimplePassiveResource as an example passive resource.

Constructor Details

ExampleTakePassiveResourceStateProbe

public ExampleTakePassiveResourceStateProbe(ASimplePassiveResource passiveResource)

Default constructor.

Parameters:

passiveResource - The observer object is a passive resource, thus, allowing to request its free resources.

Method Details

getBasicMeasure

protected javax.measure.Measure<Long,javax.measure.quantity.Dimensionless> getBasicMeasure(RequestContext measurementContext)

Measures the free resources as requested from the passive resource (observed state object).

Specified by:

getBasicMeasure in class BasicTriggeredProbe<Long,javax.measure.quantity.Dimensionless>

Parameters:

measurementContext - The measurement context for this probe.

Returns:

The new measure.
