 Logging
 =======
 
-Use your Nextcloud log to review system status, or to help debug problems. You may adjust logging levels, and choose between using the Nextcloud log or your syslog. If additional audit information is required, you can optionally activate the **admin_audit** app, which by default generates a separate audit.log file in the data directory.

+
+When ``file`` based logging is utilized, both the Nextcloud log and, optionally, the **admit_audit** app log can be viewed within the Nextcloud interface under *Administration settings -> Logging* (this functionality is provided by the **logreader** app).
+
+Further configuration and usage details for both the standard Nextcloud log and the optional **admin_audit** app log can be found below.

+By enabling the **admin_audit** app, additional information about various events can be logged. Similar to the normal logging, the audit log can be provided to any of the existing logging mechanisms in :file:`config/config.php`. The default behavior, if no parameters are specified after the app is enabled, is ``file`` based logging to a file called ``audit.log`` stored in the ``datadirectory``.

+Integrating into the Web Interface

+
+The built-in NC ``logreader`` app (which is what provides the *Administration settings->Logging* interface) only accesses the file-based ``nextcloud.log``. The **admin_audit** app log output, however, can be integrated into the web interface by configuring it to *also* log to the ``nextcloud.log``.
