Subject Re: confusion about nodetool cfstats
Date Sat, 12 Sep 2015 00:23:19 GMT
It's a single node, metric value showing just a single moment in time.
Something with historical data, aggregation across the whole cluster, etc.
may be better.  See SPM for Cassandra or OpsCenter - they come with out of
the box reports for Cassandra.
