Chris Lohfink commented on CASSANDRA-14185:
-------------------------------------------
just trying it a little bit, the output is hard to understand with the
intermixing of std out and std error. Might be nice to just go all standard out
so piping and such will be readable.

> Nodetool tablehistograms to print statics for all the tables
> ------------------------------------------------------------
>
> Key: CASSANDRA-14185
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14185
> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Reporter: Jaydeepkumar Chovatia
> Assignee: Jaydeepkumar Chovatia
> Priority: Minor
> Fix For: 4.x
>
>
> Currently {{nodetool tablehistograms}} requires {{keyspacename.tablename}} as
> argument always. If we want to print histograms for all the tables then we
> will have to run this command for all the tables one after another.
> It would be nice to have this command dump histogram for all the table at
> once if no argument is provided, similar to {{nodetool tablestats}}.
