Nodetool
Usage
usage: nodetool [(-p <port> | –port <port>)] [(-pp | –print-port)]
[(-pw <password> | –password <password>)] [(-pwf <passwordFilePath> | –password-file <passwordFilePath>)] [(-u <username> | –username <username>)] [(-h <host> | –host <host>)] <command> [<args>]
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 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. If no snapshotName is specified we will remove all snapshots 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 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 getbatchlogreplaythrottle - Print batchlog replay throttle in KB/s. This is reduced proportionally to the number of nodes in the cluster. getcompactionthreshold - Print min and max compaction thresholds for a given table getcompactionthroughput - Print the MB/s throughput cap for compaction in the system getconcurrentcompactors - Get the number of concurrent compactors in the system. getconcurrentviewbuilders - Get the number of concurrent view builders in the system getendpoints - Print the end points that owns the key getinterdcstreamthroughput - Print the Mb/s throughput cap for inter-datacenter streaming in the system getlogginglevels - Get the runtime logging levels getmaxhintwindow - Print the max hint window in ms getreplicas - Print replicas for a given key getseeds - Get the currently in use seed node IP list excluding the node IP getsstables - Print the sstable filenames that own the key getstreamthroughput - Print the Mb/s throughput cap for streaming in the system 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 handoffwindow - Print current hinted handoff window help - Display help information import - Import new SSTables to the system info - Print node information (uptime, load, …) invalidatecountercache - Invalidate the counter cache invalidatekeycache - Invalidate the key cache invalidaterowcache - Invalidate the row cache join - Join the ring listsnapshots - Lists all the snapshots along with the size on disk and true size. 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 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 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 setcompactionthreshold - Set min and max compaction thresholds for a given table setcompactionthroughput - Set the MB/s throughput cap for compaction in the system, or 0 to disable throttling setconcurrentcompactors - Set number of concurrent compactors in the system. setconcurrentviewbuilders - Set the number of concurrent view builders in the system sethintedhandoffthrottlekb - Set hinted handoff throttle in kb per second, per delivery thread. setinterdcstreamthroughput - Set the Mb/s throughput cap for 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 setstreamthroughput - Set the Mb/s throughput cap for 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 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 http://cassandra.apache.org/doc/latest/tools/nodetool/nodetool.html
