-------------------------------------------------------------------------
we should overhaul this command completely. The way it prints the statistics is
pretty ... "unique". It is actually broken, it just prints it weirdly
misaligned. There is "table layout" already widely used, I think we should just
break the output of this command and rework it completely.
We might do other stuff with various formats etc.
I have a WIP branch locally, will push later.

> 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:
> {noformat}
> Interval (ms) Max GC Elapsed (ms)Total GC Elapsed (ms)Stdev GC Elapsed (ms)
> GC Reclaimed (MB) Collections Direct Memory Bytes
