Dumping the Database Audit Logs

GaussDB(DWS) records information (audit logs) about connections and user activities in your database. With the information, you can monitor the database to ensure security and facilitate fault troubleshooting and historical operation record locating. These audit logs are stored in the database by default. You can also dump them to OBS so that users who are responsible for monitoring the database can view the logs more conveniently.

You can perform the following operations on the GaussDB(DWS) console:

Enabling Audit Log Dumps

After a data warehouse cluster is created, you can enable audit log dump for it to dump audit logs to OBS.

Before enabling audit log dump, ensure that the following conditions are met:

  • You have created an OBS bucket for storing the audit logs. For details, see "Console Operation Guide > Managing Buckets > Creating a Bucket" in the Object Storage Service User Guide.

The procedure is as follows:

  1. Log in to the GaussDB(DWS) management console.
  2. In the navigation tree on the left, click Clusters.
  3. In the cluster list, click the name of the cluster for which you want to enable audit log dump. On the page that is displayed, click Security Settings.
  4. In the Audit Settings area, enable Audit Log Dump.

    indicates that the function is enabled. indicates that the function is disabled.

    When you enable audit log dump for a project in a region for the first time, the system prompts you to create an agency named DWSAccessOBS. After the agency is created, GaussDB(DWS) can dump audit logs to OBS. By default, only Huawei Cloud accounts or users with Security Administrator permissions can create agencies. IAM users under an account do not have the permission for creating agencies by default. Contact a user with the permission and complete the authorization on the current page.

    • OBS Bucket: Name of the OBS bucket used to store the audit data. If no OBS bucket is available, click View OBS Bucket to access the OBS console and create one. For details, see Console Operation Guide > Managing Buckets > Creating a Bucket in the Object Storage Service User Guide.
    • OBS Path: User-defined directory on OBS for storing audit files. Different directory levels are separated by forward slashes (/). The value is a string containing 1 to 50 characters, which cannot start with a forward slash (/). If the entered OBS path does not exist, the system creates one and dumps data to it.
    • Dump Interval (Minute): Interval based on which GaussDB(DWS) periodically dumps data to OBS. The value ranges from 5 to 43200. The unit is minute.

  5. Click Apply.

    If Configuration Status is Applying, the system is saving the settings.

    Wait for a moment and then refresh Configuration Status. When Configuration Status is Synchronized, the configuration is saved and takes effect.

Modifying Audit Log Dump Configurations

The procedure is as follows:

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

  3. In the cluster list, click the name of the cluster for which you want to modify the audit log dump configurations. On the page that is displayed, click Security Settings.
  4. In the Audit Settings area, modify the Audit Log Dump configurations.
  5. Click Apply.

    If Configuration Status is Applying, the system is saving the settings.
