/**
 * Uses 2 timers to measure message processing rate. One for overall message processing rate and
 * another to measure rate by message type. The timers are re-used if they were previously created.
 *
 * <p>
 * {@link com.codahale.metrics.MetricRegistry} maintains a reservoir for different timers where
 * collected timings are kept. It exposes various metrics for each timer based on collected
 * data. Eg: count of messages, 99, 95, 50... percentiles, max, mean etc.
 *
 * <p>
 * These metrics are exposed as JMX bean.
