> Additional option of 'nodetool ring' command is not documented.

> {code}
>   ring                   - Print information about the token ring
> {code}

> {code}
>   ring [keyspace]        - Print information about the token ring for a given keyspace
(for all keyspaces if it is not specified)

> Some history (I think it will be useful for someone who will have the same problem):
