Patrick Bannister commented on CASSANDRA-13889:
-----------------------------------------------
I'm thinking that command line usage should support sort keys corresponding to
the keys used in the TableStatsHolder convert2Map function. They're more
verbose than I'd like, but I felt that creating a whole new nomenclature was
the worse choice.
However, I am supporting a few alternative short forms for keys I expect to get
common use:
* "read_latency" as a short form of "local_read_latency_ms"
* "reads" as a short form of "local_read_count"
* "write_latency" as a short form of "local_write_latency_ms"
* "writes" as a short form of "local_write_count"
I cringe a bit at "average_live_cells_per_slice_last_five_minutes", but I also
didn't want to blow up the command line usage hint with alternate short forms
of every key.

> When looking at a problematic node I'm not familiar with, one of the first
> things I do is check cfstats to identify the tables with the most reads,
> writes, and data. This is fine as long as there aren't a lot of tables but
> once it goes above a dozen it's quite difficult. cfstats should allow me to
> sort the results and limit to top K tables.
