Information
The log_warnings system variable, enabled by default, provides additional information to the MySQL log. A value of 1 enables logging of warning messages, and higher integer values tend to enable more logging.
Rationale:
This might help to detect malicious behavior by logging communication errors and aborted connections.
Solution
Perform the following actions to remediate this setting:
Open the MySQL configuration file (my.cnf)
Ensure the following line is found in the mysqld section
log-warnings = 2
Default Value:
The option is enabled (1) by default.
