sdb-admin describe-node [flags]
For flags that can accept multiple values (indicated by VALUES after the name of the flag),
separate each value with a comma.
Flags:
-a, --all Describe all nodes in the cluster
-h, --help Help for describe-node
--memsql-id MemsqlID The node ID of the node to describe
--property {MemsqlID, Role, AggregatorRole, ProcessState, Version, Memsqld, MemsqlConfig, Port, BindAddress, AllowIpv6, 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 File path for the Toolbox configuration
--disable-colors Disable color output in console, which some terminal sessions/environments may have difficulty with
--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
--runtime-dir DIRECTORY_PATH Where to store Toolbox runtime data
--ssh-control-persist SECONDS Enable SSH ControlPersist and set it to the specified duration in seconds
--ssh-max-sessions POSITIVE_INTEGER Maximum number of SSH sessions to open per host, must be at least 3
--ssh-strict-host-key-checking Enable strict host key checking for SSH connections
--ssh-user-known-hosts-file FILE_PATH Path to the user known_hosts file for SSH connections. If not set, /dev/null will be used
--state-file FILE_PATH Toolbox state file path
-v, --verbosity count Increase logging verbosity: valid values are 1, 2, 3. Usage -v=count or --verbosity=count
-y, --yes Enable non-interactive mode and assume the user would like to move forward with the proposed actions by default

Remarks

This command is interactive unless you use either --yes or --json flag to override interactive behavior.

Output

In the example output below you can see the types of information this command returns. For example the SingleStore (MemSQL) ID is listed, which is used in many other sdb-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.
