Ensure Audit and Gateway Log Limits Preserve Complete Statements

低级别 2人工审核tdsql

说明

audit_txsql_truncate_length limits the SQL text written by the TXSQL audit facility, while gateway.log.interface.sql_size limits the message length processed by the compute-node logging path. Both limits must be large enough to preserve complete security-relevant statements throughout the audit pipeline.

Run SHOW GLOBAL VARIABLES LIKE 'audit_txsql_truncate_length'; on the data nodes and grep -R gateway.log.interface.sql_size <tdsql>/conf/ (or check the management platform) for the compute nodes. Both must be at least 2048 bytes and large enough for the longest security-relevant statements; verify a long test statement is not truncated centrally.

修复方式

修复方法: 操作指南或基础设施补丁

Set the data-node limit through the instance parameter configuration: SET GLOBAL audit_txsql_truncate_length = 4096; Set gateway.log.interface.sql_size to the same or a larger value through the compute-node settings, then validate the complete record at the configured Kafka, Elasticsearch, DBbrain, or SIEM destination.
