public class Log4JMetricsReporter
extends PeriodicTaskComponent

This is a Log4J targeted metrics logging reporter, derived from Slf4jReporter. This implementation was built to allow for consolidating internal logging dependencies to log4j only.

Method Details

task

protected void task()

Description copied from class: UnstartedPeriodicTaskComponent

This task should only do what is needed once each period. If it throws any exceptions, then these exceptions will cause the period task to exit. Thus, if you need to allow failures in some cases while keeping the caller (scheduler) active, all errors should be caught and handled internally.

Specified by:

task in class UnstartedPeriodicTaskComponent

report

public void report(List<NBMetricGauge> gauges,
 List<NBMetricCounter> counters,
 List<NBMetricHistogram> histograms,
 List<NBMetricMeter> meters,
 List<NBMetricTimer> timers)

convertDuration

protected double convertDuration(double duration)

convertRate

protected double convertRate(double rate)

getRateUnit

protected String getRateUnit()
