Enrico Olivelli ac23f2485e Expose the global direct memory counter. (#8945) ... Motivation: This counter is very useful in order to monitor Netty without having every ByteBufAllocator in the JVM Modification: Expose the value of DIRECT_MEMORY_COUNTER as we are already doing for DIRECT_MEMORY_LIMIT. We are returning -1 in case that DIRECT_MEMORY_COUNTER is not available. Result: Be able to get the amount of direct memory used.		2019-03-19 08:35:18 +01:00
