---------------------------------------
Summary: Change description of nodetool ring command
Key: CASSANDRA-4677
URL: https://issues.apache.org/jira/browse/CASSANDRA-4677
Project: Cassandra
Issue Type: Task
Components: Tools
Affects Versions: 1.1.5
Reporter: Alexey Zotov
Priority: Trivial
Attachments: nodetool_ring_description.patch
Additional option of 'nodetool ring' command is not documented.
Old variant:
{code}
ring - Print information about the token ring
{code}
New variant
{code}
ring [keyspace] - Print information about the token ring for a given
keyspace (for all keyspaces if it is not specified)
{code}
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:

http://mail-archives.apache.org/mod_mbox/cassandra-user/201202.mbox/%[email protected]%3E
and task with fix:
https://issues.apache.org/jira/browse/CASSANDRA-3412
So you should use 'nodetool ring keyspace' for getting right information.
