      At the cache container level, disable metrics 

      <cache-container>
  <metrics gauges="false" histograms="false"/>
</cache-container>

      Another alternative is to register an implementation of io.micrometer.core.instrument.MeterRegistry

      The NullPointerException is caused by MetricsRegistry not being enabled because not MeterRegistry is in the classpath. We should not try to create metrics for sent messages if that is the case.

      Also, the second issue, the JGroupsMetricsManager should only be tracking local cluster messages and not cross-site ones.
