Method Details

shouldEmitMetric

public boolean shouldEmitMetric(Keyed key)

Description copied from interface: Emitter

Tests whether this metric object could actually be emitted based on its key. This is useful when materializing the metric object is an expensive operation.

Specified by:

shouldEmitMetric in interface Emitter

Parameters:

key - metric key to test against

Returns:

true if it is possible for this object to get emitted, false otherwise

emitMetric

public boolean emitMetric(SinglePointMetric metric)

Description copied from interface: Emitter

Emits a metric to all configured Exporter objects.

Specified by:

emitMetric in interface Emitter

Parameters:

metric - to emit

Returns:

true if exported by at least one exporter, false otherwise

flushAggregates

public void flushAggregates()
