public class MetricsTimeVaryingLong
extends MetricsBase

The MetricsTimeVaryingLong class is for a metric that naturally varies over time (e.g. number of files created). The metrics is accumulated over an interval (set in the metrics config file); the metrics is published at the end of each interval and then reset to zero. Hence the counter has the value in the current interval. Note if one wants a time associated with the metric then use

                      String description)

已过时。

Constructor - create a new metric

参数:

nam - the name of the metrics to be used to publish the metric

registry - - where the metrics object will be registered

                      MetricsRegistry registry)

已过时。

Constructor - create a new metric

参数:

nam - the name of the metrics to be used to publish the metric

registry - - where the metrics object will be registered A description of MetricsBase.NO_DESCRIPTION is used

inc

public void inc(long incr)

已过时。

Inc metrics for incr vlaue

参数:

incr - - number of operations

inc

public void inc()

已过时。

Inc metrics by one

pushMetric

public void pushMetric(MetricsRecord mr)

已过时。

Push the delta metrics to the mr. The delta is since the last push/interval. Note this does NOT push to JMX (JMX gets the info via previousIntervalValue

指定者:

pushMetric 在类中 MetricsBase

参数:

mr -
