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.
<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).
enbleautocompaction - 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.
<key>- Print the end points that owns the key.
getlogginglevels - Get the runtime logging levels.
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.
<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
[<src-dc-name>]- Rebuild data by streaming from other nodes
refresh- Load newly placed SSTables to the system without restart
<ID>- Remove node with the provided ID
<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
<value>- Sets the probability for tracing a request. Value is trace probability between 0 and 1.
[-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.
