Description

If io.netty.maxDirectMemory is not specified, Netty defaults the limit to the max heap size. Thus, direct memory in use can be significant.

However, trying this on two different platform and the result returned in gcstats is always -1:

Interval (ms) Max GC Elapsed (ms)Total GC Elapsed (ms)Stdev GC Elapsed (ms)   GC Reclaimed (MB)         Collections      Direct Memory Bytes
