README

This audit module can be used to track changes and perform audit logging on drupal sites.

Features

This module includes three plugins that facilitate logging information to Loki, files, or to the database through Drupal's watchdog logger.

These logging providers are designed using Drupal's plugin APIs. Consequently, it opens up possibilities for creating new AuditLogger plugins within other modules, thus enhancing the functionality of this audit logging.

For performance purposes we use a queue system. This avoids hindering performance more than necessary as the actual logging is done async. Furthermore, this allows for retries in case any audit log plugins should fail.

Installation

Enable the module and go to the modules setting page at /admin/config/os2web_audit/settings/.

composer require os2web/os2web_audit
drush pm:enable os2web_audit

Drush

The module provides a Drush command named audit:log. This command enables you to log a test message to the configured logger. The audit:log command accepts a string that represents the message to be logged.

The message provided, will be logged twice, once as an informational message and once as an error message.

drush audit:log 'This is a test message'

Usage

The module exposes a simple Logger service which can log an info and error messages.

Inject the logger service named os2web_audit.logger and send messages into the logger as shown below:

$msg = sprintf('Fetch personal data from service with parameter: %s', $param);
$this->auditLogger->info('Lookup', $msg);

Queue

The actual logging is handled by jobs in an Advanced Queue queue.

The queue, OS2Web audit (os2web_audit), must be processed by a server cron job, e.g.

drush advancedqueue:queue:process os2web_audit

List the queue (and all other queues) with

drush advancedqueue:queue:list

or go to /admin/config/system/queues/jobs/os2web_audit for a graphical overview of jobs in the queue.
