Reset Metrics
You can reset a group of metrics at any time. 
 When you reset a group of metrics, all the metrics in the group are reset. For example, for a server, you can reset the Queue - Report service group of metrics.
Some metrics cannot be reset. For example, JVM metrics cannot be reset because they were re-calculated after the last reset.
