MetricsRegionAggregateSourceImpl

MetricsRegionAggregateSourceImpl

public MetricsRegionAggregateSourceImpl(String metricsName,
                                        String metricsDescription,
                                        String metricsContext,
                                        String metricsJmxContext)

方法详细资料

register

public void register(MetricsRegionSource source)

指定者:

register 在接口中 MetricsRegionAggregateSource

deregister

public void deregister(MetricsRegionSource toRemove)

指定者:

deregister 在接口中 MetricsRegionAggregateSource

getMetrics

public void getMetrics(MetricsCollector collector,
                       boolean all)

Yes this is a get function that doesn't return anything. Thanks Hadoop for breaking all expectations of java programmers. Instead of returning anything Hadoop metrics expects getMetrics to push the metrics into the collector.

指定者:

getMetrics 在接口中 MetricsSource

覆盖:

getMetrics 在类中 BaseSourceImpl

参数:

collector - the collector

all - get all the metrics regardless of when they last changed.
