closed to revisit later.

> Key: CASSANDRA-6780
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6780
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Benedict
> Priority: Minor
>
> As mentioned in CASSANDRA-6689, it would be nice to expose via JMX some
> statistics on GC behaviour, instead of just optionally debug logging it (and
> maybe expand to cover some more things):
> - Time spent in GC
> - Amount of memory reclaimed
> - Number of collections (per CFS?), and average reclaimed per collection
