Yuki Morishita commented on CASSANDRA-6539:
-------------------------------------------
You need to instantiate KeyspaceMetrics object at Keyspace creation and
discard(release) when it closed. Otherwise metrics won't show up.
I honestly don't get the point of trying to aggregate all metrics from CF.
Total memtable/SSTable/BF sizes are fine, but I don't think others like max row
size/latency/BF fp ratio are not so much.
> Track metrics at a keyspace level as well as column family level
