-:Description: The location of the cluster's log file. 
+:Description: The locations of the cluster's log files. There are two channels in
+              Ceph: ``cluster`` and ``audit``. This option represents a mapping
+              from channels to log files, where the log entries of that
+              channel are sent to. The ``default`` entry is a fallback
+              mapping for channels not explicitly specified. So, the following
+              default setting will send cluster log to ``$cluster.log``, and
+              send audit log to ``$cluster.audit.log``, where ``$cluster`` will
+              be replaced with the actual cluster name.
