public class GraphiteSink
extends Object
implements org.apache.spark.metrics.sink.Sink

A Sink for Spark's metric system reporting metrics (including Beam step metrics) to Graphite.

The sink is configured using Spark configuration parameters, for example:

 "spark.metrics.conf.*.sink.graphite.class"="org.apache.beam.runners.spark.metrics.sink.GraphiteSink"
 "spark.metrics.conf.*.sink.graphite.host"="<graphite_hostname>"
 "spark.metrics.conf.*.sink.graphite.port"=<graphite_listening_port>
 "spark.metrics.conf.*.sink.graphite.period"=10
 "spark.metrics.conf.*.sink.graphite.unit"=seconds
 "spark.metrics.conf.*.sink.graphite.prefix"="<optional_prefix>"
 "spark.metrics.conf.*.sink.graphite.regex"="<optional_regex_to_send_matching_metrics>"
