Modifying Rule Template

Last updated: 2024-06-07 16:09:14

This document describes how to modify a database audit rule template in the console.          
Note:
As of September 25, 2023, the relationship between rule templates and audit instances has been adjusted from initialization to strong association. Any modification to the content of a rule template will synchronously impact the audit rule applied to instances that are bound to the rule template.
The same field of rule content can be configured with a maximum of 5 characteristic strings. And each string is separated by vertical bar"|".  
Directions    
1. Log in to the TDSQL-C for MySQL console.
2. On the left sidebar, click Database Audit.
3. Select Region and click Rule Template.      
﻿
4. Find the target rule template in the rule template list, or search for it by resource attribute in the search box, and click Edit in the Operation column.
