5.2.14 The list warnings Command

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.
