To instantiate and run the reporter execute:

OpenTSDBReporter.Builder reporter_builder =
          OpenTSDBReporter.builder()
              .withBaseUri(URI.create("http://localhost:4242")))
              .withBatchSize(64)
              .withWindowSize(60);
if (!Strings.isNullOrEmpty(tsdb.getConfig().getString(TSD_ENDPOINT))) {
  reporter_builder.withApiEndpoint("/proxy/opentsdb/api/put);
}
OpenTSDBReporter opentsdb_reporter = reporter_builder.build();
MetricRegistry metricRegistry = new MetricRegistry();
metric_registry.addReporter(opentsdb_reporter);

// on program shutdown
opentsdb_reporter.close();
