```
public final class RichGauge
extends Object
```
A gauge which stores the maximum, minimum and average in addition to the current value.
The value of the average will depend on whether a weight ('alpha') is set for the gauge. If it is unset, the average will contain a simple arithmetic mean. If a weight is set, an exponential moving average will be calculated as defined in this NIST document.

```
public RichGauge(String name)
```
    Creates an "empty" gauge. The average, max and min will be zero, but this initial value will not be included after the first value has been set on the gauge.
    参数:
    name - the name under which the gauge will be stored.
