------------------------------

             Summary: MetricsSnapshotReporter does not refresh metrics every 60 seconds
                 Key: SAMZA-349
                 URL: https://issues.apache.org/jira/browse/SAMZA-349
             Project: Samza
          Issue Type: Bug
            Reporter: Yan Fang


If my understanding is correct, the metrics we provide are for every 60 seconds and all counters will be reset every 60 seconds. Current the MetricsSnapshotReporter seems missing this implementation. It sends out the metrics every 60 seconds but does not reset the counter value.

{code}
 registry.getGroup(group).foreach {
          case (name, metric) =>
            metric.visit(new MetricsVisitor {
              def counter(counter: Counter) = groupMsg.put(name, counter.getCount: java.lang.Long)
              def gauge[T](gauge: Gauge[T]) = groupMsg.put(name, gauge.getValue.asInstanceOf[Object])
            })
        }
{code}
