When this functionality is enabled, in addition to unstructered logging, AllegroGraph provides an audit log with which important changes can be tracked and queried. The intended audience is system and database administrators conscious of security and performance.
The log resides in the

There are three contexts carrying additional information about the event. The request was received at the main port of the front end, from user "joe". It was then forwarded to the backend process with pid 4605. The main port of the backend's http server was 55713.
Regardless of security setting, only superuser has access to the system catalog.
