Warnings are not being logged

Description

The log_error_verbosity setting determines if the error log contains ERROR, WARNING, and INFORMATION messages. If WARNING messages are not printed to the error log important information may be ignored.

See log_error_verbosity for more information

Resolution

Please consider setting log_error_verbosity to a value of 2 or larger (log_warnings >= 2 for MariaDB) to avoid ignoring WARNING messages.
