Nodetool¶

Nodetool generic options¶

All options are supported:

• -p <port> or --port <port> - Remote JMX agent port number.

• -pp or --print-port - Operate in 4.0 mode with hosts disambiguated by port number.

• -pw <password> or --password <password> - Remote JMX agent password.

• -pwf <passwordFilePath> or --password-file <passwordFilePath> - Path to the JMX password file.

• -u <username> or --username <username> - Remote JMX agent username.

• -- - Separates command-line options from the list of argument(useful when an argument might be mistaken for a command-line option).

Supported Nodetool operations¶

Operations that are not listed below are currently not available.

• cfhistograms - Provides statistics about a table, including number of SSTables, read/write latency, partition size and column count.
