This document describes how to view database audit logs and their list field.
Note
A new version of the audit log page was released on July 12, 2023. The new version added a new audit log search field "Scanned Rows". For existing audit logs before this release date, the data in this field will be displayed as "-", and the corresponding downloaded files and APIs will be displayed as "-1".
The units of the audit log fields "Execution Time" and "CPU Time" in the console and downloaded audit log files are all adjusted to microseconds.
When searching audit logs, the character used to separate multiple search items is changed from comma to line break.
3. Select Region at the top, click Audit Instance tab, click Audit Status, and click Enabled to filter the audit-enabled instances.
4. Find the target instance in the Audit Instance list, or search for it by resource attribute in the search box, and click View Audit Log in the Operation column to enter the Audit Log tab and view logs.
Tool list
In the audit instance filter box, you can choose to switch to other audit instances that have enabled the audit service.
Click the time box and select a time period to view the audit logs in the selected time period.
Note
You can select any time period with data for search. Up to the first 60,000 eligible records can be displayed.
In the search box, select search items (SQL details, client IP, user account, database name, SQL type, error code, execution time (μs), lock wait time (μs), IO wait time (μs), transaction duration (μs), CPU time (μs), thread ID, scanned rows, affected rows, returned rows, etc.) to search, and you can view relevant audit results. Multiple search items are separated by line break.

Description
SQL Details
Include
Exclude
Enter the details of the SQL command and separate multiple keywords by line break.
The search of SQL command details is case-insensitive.
When the operator is "Include/Exclude", only fuzzy search by segment is supported while fuzzy search by wildcard is not.
For example, if the SQL command details are "SELECT FROM test_db LIMIT 1", you can search by segment keywords such as "SELECT", "select from", "", "SELECT FROM test_db LIMIT 1;", "from Test_DB". However, you can't search by wildcard keywords such as "SEL", "sel", and "test".
Client IP

You can filter client IP addresses by using the wildcard "" and separate them by line break. For example, if you enter "client IP: 9.223.23.2", IP addresses that start with "9.223.23.2" will be searched.
