+You can configure the *CubicWeb* instance to keep a log
+of the queries executed against your database. To do so,
+edit the configuration file of your instance
+``.../etc/cubicweb.d/myapp/all-in-one.conf`` and uncomment the
+variable ``query-log-file``::
+
+  # web instance query log file
+  query-log-file=/tmp/rql-myapp.log
