------------------------------------------
Summary: Enhance nodetool gcstats
Key: CASSANDRA-18454
URL: https://issues.apache.org/jira/browse/CASSANDRA-18454
Project: Cassandra
Issue Type: Improvement
Components: Tool/nodetool
Reporter: Brad Schoening
Nodetool gcstats reports historical GC activity:
* Interval (ms)
* Max GC Elapsed (ms)
* Total GC Elapsed (ms)
* Stdev GC Elapsed (ms)
* GC Reclaimed (MB)
* Collections
* Direct Memory Bytes
but in the MBean java.lang.GarbageCollector there are recent statistic in
events/second for:
* GcThreadCount
* Duration
It would be useful to see size of eden / survivor / old space and humongous
allocations.
