RandomNumberMetric (Jabbix library)

java.lang.Object
- org.altlinux.jabbix.metric.RandomNumberMetric

All Implemented Interfaces:

MetricAgent
```
public class RandomNumberMetric
extends java.lang.Object
implements MetricAgent
```
A sample metric agent for the Jabbix library querying the random number generator for a value of a normally distributed random number. Because of only one metric to return it is returned for any given key.
