Description

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

Old variant:

  ring                   - Print information about the token ring

New variant

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

Patch has been attached.

Some history (I think it will be useful for someone who will have the same problem):
I have 4-nodes cluster. One of nodes is located in other DC (DC2). I've met the problem that 'nodetool ring' shows that node in DC2 'Owns 0.00%'. I've found following questions:

and task with fix:
https://issues.apache.org/jira/browse/CASSANDRA-3412

So you should use 'nodetool ring keyspace' for getting right information.
