Hi Kevin,

In many cases variation is a way more informative than an absolute value indeed. I have a doubt regarding your approach though. I want to see IO throughput and load on C* for each table. > +1 on Kurt comment: Anything in cfstats you should be able to retrieve through the metrics > Mbeans. See https://cassandra.apache.org/doc/latest/operating/metrics.html I do not use 'nodetool cfstats' that much. As soon as a monitoring system is in place, I prefer using a chart, making things a way more obvious, with no need to build anything on top of nodetool cfstats. Plus you can mix the chart with other relevant and related informations. That's probably the best way to go for production.
