Class JmxMetricsReporter

java.lang.Object

org.apache.solr.metrics.reporters.jmx.JmxMetricsReporter

All Implemented Interfaces:

com.codahale.metrics.Reporter, Closeable, AutoCloseable

public class JmxMetricsReporter
extends Object
implements com.codahale.metrics.Reporter, Closeable

This is a modified copy of Dropwizard's JmxReporter and classes that it internally uses, with a few important differences:

• this class knows that it can directly use MetricsMap as a dynamic MBean.
• this class allows us to "tag" MBean instances so that we can later unregister only instances registered with the same tag.
• this class processes all metrics already existing in the registry at the time when reporter is started.
