Advanced Namespace

The advanced namespace has six commands and is based on adding and managing system settings found in the SCALE API and web UI. It provides access to advanced system settings and functions through the advanced commands.

Advanced Commands

The following advanced commands allow you to add new and manage advanced system settings.

You can enter commands from the main CLI prompt or from the advanced namespace prompt.

Interactive Argument Editor (TUI)

Enter the -- flag following any CLI command to open the interactive arguments editor text-based user interface (TUI).

Click for more information

The interactive argument editor is a text user interface (TUI) that can help enter complex commands with multiple configurable properties. It shows expected properties, defaults, input types (string, boolean, integer, or array), and can include command instructions or warnings.

Optional properties, indicated by the # symbol, are disabled by default. Required properties are enabled. Do not disable properties that are enabled by default.

To configure required properties, enter a space after the colon then add the value.

To enable optional properties, delete # from the corresponding line.

Some required properties are disabled if they are part of a pair of properties where one or the other is required. Select one property to enable and enter a value.

Press F2 or click Save to save the modified file.

Press F10, Esc, or click Quit to exit the TUI. The command automatically executes upon exit.

Config Command

The config command lists current advanced settings for the system.

Using the Config Command

Description

The config command does not require entering a property argument. Enter the command then press Enter. The command returns a table with advanced system settings (see list of Update Properties for details).

PropertyDescriptionSyntax Example
boot_scrubRepresents the number of days between boot pool scrubs. Enter a numeric value.boot_scrub=8
consolemenuSet consolemenu to false to default to standard login or to true to show the console menu.consolemenu=true
consolemsgDeprecated. Removal of consolemsg is planned in a future release. Use system general update ui_consolemsg property to display console messages in real time at the bottom of the UI browser.N/A
debugkernelSet to true to include the kernel debug when generating a debug file. After the next system reboot, the debug file includes kernel debug information.debugkernel=true
fqdn_syslogSet to true to include the Fully-Qualified Domain Name (FQDN) in logs to precisely identify systems with similar hostnames.fqdn_syslog=true
motdEnter the message to display when a user logs in with SSH.motd="Display this text"
serialconsoleSet to true to enable the serial console but do not enable if the serial port is disabled.serialconsole=true
serialportEnter the serial port address.serialport="serialPort"

Use nonstandard port numbers by adding a colon and the port number to the hostname, like mysyslogserver:1928. Log entries are written to local logs and sent to the remote syslog server.syslogserver=​"remoteIP:portNumber"
syslog_transportTransport protocol for the remote system log server connection. Choosing Transport Layer Security (TLS) also requires setting a preconfigured system certificate. Options are: UDP, TCP, TLS.syslog_transport=TCP
