------------------------------------------
Summary: Backport fix to nodetool gcstats output
Key: CASSANDRA-21037
URL: https://issues.apache.org/jira/browse/CASSANDRA-21037
Project: Apache Cassandra
Issue Type: Bug
Components: Tool/nodetool
Reporter: Brad Schoening
Assignee: Ling Mao
Fix For: 5.1
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

41276288089024 6120 -1{noformat}
