Ensure the Slow Query Log Is Enabled

低级别 1自动化tdsql

说明

The slow query log records SQL statements whose execution time exceeds a specified threshold, helping to identify performance issues and potential DoS attacks. Runs the mysql client against the TDSQL data node selected by TDSQL_MYSQL_OPTS (e.g. "-h10.0.0.5 -P4001 -utdsql_audit"); keep the password in ~/.my.cnf or a login path rather than MYSQL_PWD or the command line (see 1.4 and 1.5). Passes when slow_query_log is ON and long_query_time is between 1 and 10 seconds.
