Configuring the Database Audit Logs

Prerequisites

Database audit logs are configured on the Security Settings page. You can change security settings only when the cluster status is Available and Unbalanced, and Task Information cannot be Creating snapshot, Changing all specifications, Configuring, or Restarting.

Procedure

  1. Log in to the GaussDB(DWS) management console.

  2. Click Clusters.

  3. In the cluster list, click the name of a cluster. Choose Security.

    By default, Configuration Status is Synchronized, which indicates that the latest database results are displayed.

  4. In the Audit Settings area, configure the audit log retention policy.

    image1

    Space priority: Audit logs will be automatically deleted if the size of audit logs on a single node exceeds 1 GB.

    Caution

    • Clusters 1.0.0 and 1.1.0 do not support audit log retention.

    • If the planned storage space of the database is limited, select Space priority to prevent faulty nodes or low performance caused by insufficient disk space.

  5. Enable the audit function for the following operations if necessary.

    Table 1 describes the detailed information about the audit items.
