-----------------------------------
Summary: Memtable OffHeap GC Statistics
Key: CASSANDRA-6780
URL: https://issues.apache.org/jira/browse/CASSANDRA-6780
Project: Cassandra
Issue Type: Improvement
Reporter: Benedict
Assignee: 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
