+### Queue
+
+The actual logging is handled by jobs in an [Advanced
+Queue](https://www.drupal.org/project/advancedqueue) queue.
+
+The queue, OS2Web audit (`os2web_audit`), must be
+processed by a server `cron` job, e.g.
+
+```sh
+drush advancedqueue:queue:process os2web_audit

+
+List the queue (and all other queues) with

+drush advancedqueue:queue:list

+graphical overview of jobs in the queue.
