Metric

```
@Retention(value=RUNTIME)
 @Target(value={FIELD,PARAMETER,ANNOTATION_TYPE})
public @interface Metric
```
An annotation requesting that a metric be injected or registered. The metric will be registered in the application MetricRegistry. Given an injected field annotated with @Metric like this:
```
      @Inject
      @Metric(name="histogram")
     public Histogram histogram;
 
```
A meter of the field's type will be created and injected into managed objects. It will be up to the user to interact with the metric. This annotation can be used on fields of type Meter, Timer, SimpleTimer, Counter, and Histogram.
This may also be used to register a metric.
