+You can configure the `CubicWeb` application so that you keep a log
+of the queries executed against your database. To do so, you want to

+``.../etc/cubicweb.d/myapp/all-in-one.conf`` and uncomment the
+variable ``query-log-file``: ::
+
+  # web application query log file
+  query-log-file=/tmp/rql-myapp.log
