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 the --yes or --json flags to override interactive behavior.

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 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.
