    Description

      The Java NIO subsystem uses buffers allocated in off-heap memory to manage certain types of I/O operations. We should expose the count and bytes used by these buffers in the default status output in order to enable detection of leaks or other problems with this area of memory usage:

      curl -k 'https://localhost:8140/metrics/v2/read/java.nio:type=BufferPool,*/Count,MemoryUsed,TotalCapacity'
