GaugeRuntime	Main entry point for working with gauges, which are simple sensors that measure the value of a single numeric property.

Package net.sf.sensor.gauge Description

This package provides support for measuring simple (numeric) properties of runtime components.

A Gauge represents such a runtime property and the current value of that property can be retrieved through the getValue() method. Gauges are classes that implement the Gauge interface. The net.sf.sensor.gauge.support package offers a number of default implementations that can be used out of the box.

To use a Gauge, it needs to be registered with the GaugeRuntime using the addGauge(Gauge) method. The GaugeRuntime will usually be a (Spring-)managed singleton but a static instance can also be retrieved using the StaticSensorRuntime.getGaugeRuntime() method.
