12.2 Verbose Output

From MySQL 8.0.17, you can send MySQL Shell logging information to the console to help with debugging. Logging messages sent to the console are given the verbose: prefix. When you send logging information to the console, it is still sent to the application log file.

To send logging information to the console as verbose output, choose one of these options:

• Use the --verbose command-line option when starting MySQL Shell.

• Use the MySQL Shell \option command to set the verbose MySQL Shell configuration option. For instructions to use this command, see Section 13.4, “Configuring MySQL Shell Options”.

• Use the shell.options object to set the verbose MySQL Shell configuration option. For instructions to use this configuration interface, see Section 13.4, “Configuring MySQL Shell Options”.

The available settings are as listed in Table 12.1, “Logging levels in MySQL Shell”. The settings for the verbose option display messages at the following levels of detail:

0

No messages. Equivalent to a logging level of 1 for the application log.

1

Internal error, error, warning, and informational messages. Equivalent to a logging level of 5 for the application log.

2

Adds debug messages. Equivalent to a logging level of 6 for the application log.

3

Adds debug2 messages. Equivalent to a logging level of 7 for the application log.

4

Adds debug3 messages, the highest level of detail. Equivalent to a logging level of 8 for the application log.

If the verbose option is not set on the command line or in the configuration file, or if you specify a setting of 0 for the option, verbose output to the console is disabled. All other values enable verbose output and set the level of detail for the messages sent to the console. If you specify the option without a value, which is permitted as a command-line option when starting MySQL Shell (--verbose) but not with other methods of setting the option, setting 1 (internal error, error, warning, and informational messages) is used.
