Examples of MetricsTimeVaryingRate

org.apache.hadoop.metrics.util.MetricsTimeVaryingRate
The MetricsTimeVaryingRate class is for a rate based metric that naturally varies over time (e.g. time taken to create a file). The rate is averaged at each interval heart beat (the interval is set in the metrics config file). This class also keeps track of the min and max rates along with a method to reset the min-max.
