The nodetool utility provides a simple command-line interface to the following exposed operations and attributes. Scylla’s nodetool is a fork of the Apache Cassandra nodetool with the same syntax and a subset of the operations.

Nodetool generic options

All options are supported:

( -h | --host ) <host name> | <ip address>
( -p | --port ) <port number>
( -pw | --password ) <password >
( -u | --username ) <user name>
( -pwf <passwordFilePath | --password-file <passwordFilePath> )

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.

  • cfstats - Provides in-depth diagnostics regard table.

  • cleanup - Triggers the immediate cleanup of keys no longer belonging to a node.

  • clearsnapshot - This command removes snapshots.

  • compactionhistory - Provides the history of compactions.

  • compactionstats- Print statistics on compactions.

  • compact- Force a (major) compaction on one or more column families.

  • decommission - Decommission the node.

  • describecluster - Print the name, snitch, partitioner and schema version of a cluster.

  • describering - <keyspace>- Shows the partition ranges of a given keyspace.

  • disableautocompaction - Disable automatic compaction of a keyspace or table.

  • disablebackup - Disable incremental backup.

  • disablebinary - Disable native transport (binary protocol).

  • disablegossip - Disable gossip (effectively marking the node down).

  • drain - Drain the node (stop accepting writes and flush all column families).

  • enableautocompaction - Enable automatic compaction of a keyspace or table.

  • enablebackup - Enable incremental backup.

  • enablebinary - Reenable native transport (binary protocol).

  • enablegossip - Reenable gossip.

  • flush - Flush one or more column families.

  • getendpoints <keyspace> <table> <key>- Print the end points that owns the key.

  • getlogginglevels - Get the runtime logging levels.

  • gettraceprobability - Displays the current trace probability value. 0 is disabled 1 is enabled.

  • gossipinfo - Shows the gossip information for the cluster.

  • help - Display list of avilable nodetool commands.

  • info - Print node information

  • listsnapshots - Lists all the snapshots along with the size on disk and true size.

  • move <new token>- Move node on the token ring to a new token

  • netstats - Print network information on provided host (connecting node by default)

  • proxyhistograms - Print statistic histograms for network operations

  • rebuild [<src-dc-name>]- Rebuild data by streaming from other nodes

  • refresh- Load newly placed SSTables to the system without restart

  • removenode- Remove node with the provided ID

  • repair <keyspace> <table> - Repair one or more tables

  • ring - The nodetool ring command display the token ring information.

  • setlogginglevel - sets the logging level threashold for Scylla classes

  • settraceprobability <value> - Sets the probability for tracing a request. race probability value

  • snapshot [-t tag] [-cf column_family] <keyspace> - Take a snapshot of specified keyspaces or a snapshot of the specified table.

  • statusbackup - Status of incremental backup.

  • statusbinary - Status of native transport (binary protocol).

  • statusgossip - Status of gossip.

  • status - Print cluster information.

  • stop compaction - Stop compaction operation.

  • tablehistograms see cfhistograms

  • tablestats - Provides in-depth diagnostics regard table.

  • toppartitions - Samples cluster writes and reads and reports the most active partitions in a specified table and time frame.

  • upgradesstables - Upgrades each table that is not running the latest Scylla version, by rewriting SSTables.

  • viewbuildstatus - Shows the progress of a materialized view build.

  • version - Print the DB version.
