About the nodetool utility

A command line interface for managing a cluster.

The nodetool utility is a command line interface for managing a cluster.

Command formats 

C:\> %CASSANDRA_HOME%\bin\nodetool [options] command [args]
Options
Short Long Description
-h --host Hostname or IP address.
-p --port Port number.
-pwf --password-file Password file path.
-pw --password Password.
-u --username Remote JMX agent username.
Note:
  • If a username and password for RMI authentication are set explicitly in the cassandra-env.ps1 file for the host, then you must specify credentials.
  • The repair and rebuild commands can affect multiple nodes in the cluster.
  • Most nodetool commands operate on a single node in the cluster if -h is not used to identify one or more other nodes. If the node from which you issue the command is the intended target, you do not need the -h option to identify the target; otherwise, for remote invocation, identify the target node, or nodes, using -h.
