registry - - where the metrics object will be registered

description - metrics description

PersistentMetricsTimeVaryingRate

public PersistentMetricsTimeVaryingRate(String nam,
                                org.apache.hadoop.metrics.util.MetricsRegistry registry)

Deprecated.

Constructor - create a new metric

Parameters:

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

registry - - where the metrics object will be registered

Method Detail

pushMetric

public void pushMetric(org.apache.hadoop.metrics.MetricsRecord mr)

Deprecated.

Push updated metrics to the mr. Note this does NOT push to JMX (JMX gets the info via MetricsTimeVaryingRate.getPreviousIntervalAverageTime() and MetricsTimeVaryingRate.getPreviousIntervalNumOps()

Overrides:

pushMetric in class org.apache.hadoop.metrics.util.MetricsTimeVaryingRate

Parameters:

mr - owner of this metric

inc

public void inc(int numOps,
       long time)

Deprecated.

Increment the metrics for numOps operations

Overrides:

inc in class org.apache.hadoop.metrics.util.MetricsTimeVaryingRate

Parameters:

numOps - - number of operations

time - - time for numOps operations

inc

public void inc(long time)

Deprecated.

Increment the metrics for numOps operations

Overrides:

inc in class org.apache.hadoop.metrics.util.MetricsTimeVaryingRate

Parameters:

time - - time for numOps operations

resetMinMaxAvg

public void resetMinMaxAvg()

Deprecated.

Rollover to a new interval NOTE: does not reset numOps. this is an absolute value

maintainStats

protected void maintainStats()

Deprecated.
