metricName - the name of the metric

group - the group that contains the metric

notifyOfRemovedMetric

public void notifyOfRemovedMetric(Metric metric,
                                  String metricName,
                                  MetricGroup group)

Called when a Metric was removed.

Specified by:

notifyOfRemovedMetric in interface MetricReporter

Parameters:

metric - the metric that should be removed

metricName - the name of the metric

group - the group that contains the metric

open

public void open(MetricConfig config)

Description copied from interface: MetricReporter

Configures this reporter.

If the reporter was instantiated generically and hence parameter-less, this method is the place where the reporter sets it's basic fields based on configuration values. Otherwise, this method will typically be a no-op since resources can be acquired in the constructor.

This method is always called first on a newly instantiated reporter.

Specified by:

open in interface MetricReporter

Parameters:

config - A properties object that contains all parameters set for this reporter.

close

public void close()

Description copied from interface: MetricReporter

Closes this reporter. Should be used to close channels, streams and release resources.

Specified by:

close in interface MetricReporter

report

public void report()

Description copied from interface: Scheduled

Report the current measurements. This method is called periodically by the metrics registry that uses the reporter. This method must not block for a significant amount of time, any reporter needing more time should instead run the operation asynchronously.

Specified by:

report in interface Scheduled
