    Usage

    usage: nodetool [(-pp | —print-port)] [(-pw | —password )] [(-p | —port )] [(-h | —host )] [(-pwf | —password-file )] [(-u | —username )] [] The most commonly used nodetool commands are: assassinate - Forcefully remove a dead node without re-replicating any data. Use as a last resort if you cannot removenode bootstrap - Monitor/manage node’s bootstrap process checktokenmetadata - compares - the Gossip endpointState and TokenMetadata cache; printing any mismatches found cleanup - Triggers the immediate cleanup of keys no longer belonging to a node. By default, clean all keyspaces clearsnapshot - Remove the snapshot with the given name from the given keyspaces clientstats - Print information about connected clients compact - Force a (major) compaction on one or more tables or user-defined compaction on given SSTables compactionhistory - Print history of compaction compactionstats - Print statistics on compactions datapaths - Print all directories where data of tables are stored decommission - Decommission the node I am connecting to describecluster - Print the name, snitch, partitioner and schema version of a cluster describering - Shows the token ranges info of a given keyspace disableauditlog - Disable the audit log disableautocompaction - Disable autocompaction for the given keyspace and table disablebackup - Disable incremental backup disablebinary - Disable native transport (binary protocol) disablefullquerylog - Disable the full query log disablegossip - Disable gossip (effectively marking the node down) disablehandoff - Disable storing hinted handoffs disablehintsfordc - Disable hints for a data center disableoldprotocolversions - Disable old protocol versions drain - Drain the node (stop accepting writes and flush all tables) enableauditlog - Enable the audit log enableautocompaction - Enable autocompaction for the given keyspace and table enablebackup - Enable incremental backup enablebinary - Reenable native transport (binary protocol) enablefullquerylog - Enable full query logging, defaults for the options are configured in cassandra.yaml enablegossip - Reenable gossip enablehandoff - Reenable future hints storing on the current node enablehintsfordc - Enable hints for a data center that was previsouly disabled enableoldprotocolversions - Enable old protocol versions failuredetector - Shows the failure detector information for the cluster flush - Flush one or more tables garbagecollect - Remove deleted data from one or more tables gcstats - Print GC Statistics getauditlog - Print configuration of audit log if enabled, otherwise the configuration reflected in cassandra.yaml getauthcacheconfig - Get configuration of Auth cache getbatchlogreplaythrottle - Print batchlog replay throttle in KB/s. This is reduced proportionally to the number of nodes in the cluster. getcolumnindexsize - Print the granularity of the collation index of rows within a partition in KiB getcompactionthreshold - Print min and max compaction thresholds for a given table getcompactionthroughput - Print the MiB/s throughput cap for compaction in the system as a rounded number getconcurrency - Get maximum concurrency for processing stages getconcurrentcompactors - Get the number of concurrent compactors in the system. getconcurrentviewbuilders - Get the number of concurrent view builders in the system getdefaultrf - Gets default keyspace replication factor. getendpoints - Print the end points that owns the key getfullquerylog - Print configuration of fql if enabled, otherwise the configuration reflected in cassandra.yaml getinterdcstreamthroughput - Print the throughput cap for inter-datacenter streaming and entire SSTable inter-datacenter streaming in the systemin rounded megabits. For precise number, please, use option -d getlogginglevels - Get the runtime logging levels getmaxhintwindow - Print the max hint window in ms getseeds - Get the currently in use seed node IP list excluding the node IP getsnapshotthrottle - Print the snapshot_links_per_second throttle for snapshot/clearsnapshot getsstables - Print the sstable filenames that own the key getstreamthroughput - Print the throughput cap for streaming and entire SSTable streaming in the system in rounded megabits. For precise number, please, use option -d gettimeout - Print the timeout of the given type in ms gettraceprobability - Print the current trace probability value gossipinfo - Shows the gossip information for the cluster help - Display help information import - Import new SSTables to the system info - Print node information (uptime, load, …​) invalidatecountercache - Invalidate the counter cache invalidatecredentialscache - Invalidate the credentials cache invalidatejmxpermissionscache - Invalidate the JMX permissions cache invalidatekeycache - Invalidate the key cache invalidatenetworkpermissionscache - Invalidate the network permissions cache invalidatepermissionscache - Invalidate the permissions cache invalidaterolescache - Invalidate the roles cache invalidaterowcache - Invalidate the row cache join - Join the ring listpendinghints - Print all pending hints that this node has listsnapshots - Lists all the snapshots along with the size on disk and true size. True size is the total size of all SSTables which are not backed up to disk. Size on disk is total size of the snapshot on disk. Total TrueDiskSpaceUsed does not make any SSTable deduplication. move - Move node on the token ring to a new token netstats - Print network information on provided host (connecting node by default) pausehandoff - Pause hints delivery process profileload - Low footprint profiling of activity for a period of time proxyhistograms - Print statistic histograms for network operations rangekeysample - Shows the sampled keys held across all keyspaces rebuild - Rebuild data by streaming from other nodes (similarly to bootstrap) rebuild_index - A full rebuild of native secondary indexes for a given table recompress_sstables - Rewrite sstables (for the requested tables) that have compression configuration different from the current refresh - Load newly placed SSTables to the system without restart refreshsizeestimates - Refresh system.size_estimates reloadlocalschema - Reload local node schema from system tables reloadseeds - Reload the seed node list from the seed node provider reloadssl - Signals Cassandra to reload SSL certificates reloadtriggers - Reload trigger classes relocatesstables - Relocates sstables to the correct disk removenode - Show status of current node removal, force completion of pending removal or remove provided ID repair - Repair one or more tables repair_admin - list - and fail incremental repair sessions replaybatchlog - Kick off batchlog replay and wait for finish resetfullquerylog - Stop the full query log and clean files in the configured full query log directory from cassandra.yaml as well as JMX resetlocalschema - Reset node’s local schema and resync resumehandoff - Resume hints delivery process ring - Print information about the token ring scrub - Scrub (rebuild sstables for) one or more tables setauthcacheconfig - Set configuration for Auth cache setbatchlogreplaythrottle - Set batchlog replay throttle in KB per second, or 0 to disable throttling. This will be reduced proportionally to the number of nodes in the cluster. setcachecapacity - Set global key, row, and counter cache capacities (in MB units) setcachekeystosave - Set number of keys saved by each cache for faster post-restart warmup. 0 to disable setcolumnindexsize - Set the granularity of the collation index of rows within a partition in KiB setcompactionthreshold - Set min and max compaction thresholds for a given table setcompactionthroughput - Set the MiB/s throughput cap for compaction in the system, or 0 to disable throttling setconcurrency - Set maximum concurrency for processing stage setconcurrentcompactors - Set number of concurrent compactors in the system. setconcurrentviewbuilders - Set the number of concurrent view builders in the system setdefaultrf - Sets default keyspace replication factor. sethintedhandoffthrottlekb - Set hinted handoff throttle in KiB per second, per delivery thread. setinterdcstreamthroughput - Set the throughput cap for inter-datacenter streaming and entire SSTable inter-datacenter streaming in the system, or 0 to disable throttling setlogginglevel - Set the log level threshold for a given component or class. Will reset to the initial configuration if called with no parameters. setmaxhintwindow - Set the specified max hint window in ms setsnapshotthrottle - Set the snapshot_links_per_second cap for snapshot and clearsnapshot throttling setstreamthroughput - Set throughput cap for streaming and entire SSTable streaming in the system, or 0 to disable throttling settimeout - Set the specified timeout in ms, or 0 to disable timeout settraceprobability - Sets the probability for tracing any given request to value. 0 disables, 1 enables for all requests, 0 is the default sjk - Run commands of ‘Swiss Java Knife’. Run ‘nodetool sjk —help’ for more information. snapshot - Take a snapshot of specified keyspaces or a snapshot of the specified table status - Print cluster information (state, load, IDs, …​) statusautocompaction - status - of autocompaction of the given keyspace and table statusbackup - Status of incremental backup statusbinary - Status of native transport (binary protocol) statusgossip - Status of gossip statushandoff - Status of storing future hints on the current node stop - Stop compaction stopdaemon - Stop cassandra daemon tablehistograms - Print statistic histograms for a given table tablestats - Print statistics on tables toppartitions - Sample and print the most active partitions tpstats - Print usage statistics of thread pools truncatehints - Truncate all hints on the local node, or truncate hints for the endpoint(s) specified. upgradesstables - Rewrite sstables (for the requested tables) that are not on the current version (thus upgrading them to said current version) verify - Verify (check data checksum for) one or more tables version - Print cassandra version viewbuildstatus - Show progress of a materialized view build See ‘nodetool help ’ for more information on a specific command.
