MySQL Cluster Manager 9.0 Release Notes
        
list warnings [--max=n]
        Using this command, you can check important warnings issued
        across the whole site during the executions of MySQL Cluster Manager client
        commands since the agent was started (or restarted). It provides
        additional information that is not exposed by the
        show warnings command. Use the
        --max option to
        specify the maximum number of warnings to be returned by this
        command. The default value for the option is 5, and the maximum
        value is 100.
