Here the ring command prints each node's status and the assigned tokens for each
Cassandra node. The output shows the data nodes' IP addresses, their statuses, and rack
information:
•
The
Address
column shows the nodes' URL or IP address.
•
The
Rack
column contains rack information.
•
If the nodes are live and are part of the cluster ring, their status will be
Up
; otherwise, it will be
Down
.
•
Possible values for
State
are
Normal
,
Leaving
,
Joining,
and
Moving
.
•
If a data node is part of cluster ring it will be shown with status as
Normal
.
•
If a node is getting decommissioned, then it will have an intermediate
state of
Leaving
.
•
The status will be
Moving
if the node has been moved to another
token value.
•
The
Load
column displays the current data load on each node. This in-
formation is important from an administration perspective as load and
ownership (the
Owns
column) information show whether the ring is in a
balanced state.
•
The
Token
column shows the assigned token, which is a token range.
