Field Detail

REPORTERS_LIST

public static final ConfigOption<String> REPORTERS_LIST

An optional list of reporter names. If configured, only reporters whose name matches any of the names in the list will be started. Otherwise, all reporters that could be found in the configuration will be started.

Example:

 metrics.reporters = foo,bar

 metrics.reporter.foo.class = org.apache.flink.metrics.reporter.JMXReporter
 metrics.reporter.foo.interval = 10

 metrics.reporter.bar.class = org.apache.flink.metrics.graphite.GraphiteReporter
 metrics.reporter.bar.port = 1337
