Downloading SQL Audit Logs

If you enable SQL audit, the system records all SQL operations and uploads logs every half an hour or when the size is accumulated to 100 MB. You can download audit logs to view details. The minimum time unit of audit logs is second. By default, SQL audit is disabled. Enabling this function may affect database performance.

Procedure

Log in to the management console.
Click in the upper left corner and select a region.
Click in the upper left corner of the page and choose Databases > Relational Database Service.
On the Instances page, click the target instance name.
In the navigation pane on the left, choose SQL Audits.
On the displayed page, select a time range in the upper right corner, select SQL audit logs to be downloaded in the list, and click Download above the list to download SQL audit logs in batches.

Alternatively, select an audit log and click Download in the Operation column to download an individual SQL audit log.

You are advised to download no more than six audit log files at a time. Too many files can fail to be downloaded completely due to the limit on the number of concurrent requests of the browser.

The following figure shows the SQL audit log content. For field descriptions, see Table 1.
