Nodetool statusCopy
status - This command prints the cluster information for a single keyspace or all keyspaces.
The keyspace argument is required to calculate effective ownership information (Owns column).
For tablet keyspaces, a table is also required for effective ownership.
For example:
nodetool status my_keyspace
Example output:
Datacenter: datacenter1
