--memsql-id MemsqlID MemSQL ID to describe
--property {MemsqlID, Role, ProcessState, Version, Memsqld, MemsqlConfig, Port, BindAddress, Datadir, Tracelogsdir, Plancachedir, Auditlogsdir, IsConnectable, Pid, DPid, AutoRestartEnabled, RecoveryState, AvailabilityGroup, Host, NodeID, Config[.${CONFIG_NAME}], Variables[.${VARIABLE_NAME}]} Only output the value of this property (default Unspecified)
Global Flags:
--backup-cache FILE_PATH File path for the backup cache
--cache-file FILE_PATH File path for the Toolbox node cache
-c, --config FILE_PATH Toolbox configuration file path
--disable-spinner Disable the progress spinner, which some terminal sessions/environments may have issues with
-j, --json Enable JSON output
--parallelism POSITIVE_INTEGER Maximum number of operations to run in parallel

Output
In the example output below you can see the types of information this command returns. For example the MemSQL ID is listed, which is used in many other memsql-admin commands. We can also see this information was collected for the master aggregator node, because the role indicates: Master.
Additionally the config, data, plancache, logs, and the binary are all at their default paths, which includes a node-specific hash. If you are using a config management system then you might need to customize these paths. They can be configured either as engine variables, or in the memsqlctl state and config files.
