MetricsTableAggregateSourceImpl

MetricsTableAggregateSourceImpl

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

方法详细资料

deleteTableSource

public void deleteTableSource(String table)

指定者:

deleteTableSource 在接口中 MetricsTableAggregateSource

getOrCreateTableSource

public MetricsTableSource getOrCreateTableSource(String table,
                                                 MetricsTableWrapperAggregate wrapper)

指定者:

getOrCreateTableSource 在接口中 MetricsTableAggregateSource

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.
