Enable Auditing

This page explains how to enable auditing for a database.

The auditing function in Exasol captures details for every session and every executed SQL statement. Auditing is enabled by default on a new database. For more information, see Auditing.

This procedure is carried out using ConfD.

Prerequisites

The database must be stopped. For more information, see Stop a Database.

Procedure

The following examples use ConfD through the command-line tool confd_client, which is available on all database nodes. You can also access ConfD through XML-RPC in your own Python programs. For more information, see ConfD.

  1. Connect to EXAClusterOS (COS) using c4 connect -t <DEPLOYMENT>[.<NODE>]/cos. For example:

    c4 connect -t 1/cos

    In most cases it does not matter on which node you access ConfD. If you do not specify a node, c4 will connect to the first active node in the deployment. If the cluster is configured with an access node, the first node is the access node (usually n10). The command prompt in COS indicates which node you are connected to: 

    [root@n10 ~]#

    For more information about how to use c4 connect, see How to use c4.

  2. To find the name of the database, use the ConfD job db_list. For example:

    confd_client db_list
    - MY_DATABASE

  3. If the database is running, stop it now using the ConfD job db_stop. For example:

    confd_client db_stop db_name: MY_DATABASE

  4. To enable auditing, use the ConfD job db_configure and set enable_auditing to true. For example:

    confd_client db_configure db_name: MY_DATABASE, enable_auditing: true

  5. Start the database using the ConfD job db_start. For example:

    confd_client db_start db_name: MY_DATABASE

Verification

To verify that the database is configured with the new properties, use the ConfD job db_info. For example: 

confd_client db_info db_name: MY_DATABASE
