+Data Attributes-only Monitoring
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Data access is the primary monitoring information for DAMON.  Hence it
+:ref:`adjusts <damon_design_data_attrs_monitoring>` regions using the access
+:ref:`counter <damon_design_region_based_sampling>` (``nr_accesses``).  In some
+use cases, however, users may want some of :ref:`attributes
+<damon_design_data_attrs_monitoring>` to be the primary information.
+
+Data attributes-only monitoring mode supports this use case.  For the mode,
+each attribute probe has their priority weight value.  Users can describe by
+what combination of the attributes the primary information is decided, by
+setting the priority weight value.  If the total sum of the weights is not
+zero, the mode is enabled.  The regions adjustment mechanism uses the weighted
+sum of the :ref:`probe hit counts <damon_design_data_attrs_monitoring>` instead
+of ``nr_accesses`` in the case.  When the mode is enabled, access monitoring is
+automatically turned off.  The access counter (``nr_accesses``) will always be
+zero and not updated.  Hence the mode is called Data Attributes "only"
+monitoring.
