     The main group-level options here are:
 
     *   ``roles``: This option enables the ``roles.crud-router`` :ref:`role <configuration_application_roles_enable>` provided by the CRUD module for a router instance.
-    *   ``roles_cfg``: This section enables and configures statistics on called operations for a router with the enabled ``roles.crud-router`` role.
     *   ``app``: The ``app.module`` option specifies that code specific to a router should be loaded from the ``router`` module. This is explained below in the :ref:`vshard-quick-start-router-code` section.
     *   ``sharding``: The :ref:`sharding.roles <configuration_reference_sharding_roles>` option specifies that an instance inside this group acts as a router.
     *   ``replicasets``: This section configures a replica set with one router instance.
