Ensure TXSQL Auditing Is Enabled on All Data Nodes

AltaNivel 1Automatizadatdsql

Descripción

TDSQL provides the audit_txsql audit facility to record SQL activity on TXSQL data nodes. Auditing must be enabled consistently on every primary and replica in every shard so that a node switch or distributed query cannot create an audit blind spot. ALL mode records all SQL activity. FILTER mode uses database, source-IP, and user exclusion lists and therefore requires a formally approved exception. 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). The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Run against every primary and replica of every shard. Passes when the audit_txsql plugin is ACTIVE, audit_txsql_audit_mode = ALL and the db/ip/user filters are empty; also confirm audit files are written in audit_txsql_audit_dir with complete records.

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

SET GLOBAL audit_txsql_audit_mode = 'ALL'; (with empty audit_txsql_filter_db/ip/user) through a TDSQL custom parameter template associated with every instance.
