public class JvmBufferPoolMetrics extends Object
JVM Buffer Pool metrics. The JvmBufferPoolMetrics are registered as part of the JvmMetrics like this: 

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

   JvmBufferPoolMetrics.builder().register();
Example metrics being exported:
