JvmMemoryMetrics
public class JvmMemoryMetrics extends Object
JVM memory metrics. The JvmMemoryMetrics are registered as part of the JvmMetrics like this: 

 JvmMetrics.builder().register();
However, if you want only the JvmMemoryMetrics you can also register them directly: 

 JvmMemoryMetrics.builder().register();
