204 Files for specifying attributes of the monitoring including required quality
205 and efficiency of the monitoring are in ``monitoring_attrs`` directory.
215 of DAMON's monitoring regions (``min`` and ``max``, respectively), which
216 controls the monitoring overhead, exist.  You can set and get the values by
219 For more details about the intervals and monitoring regions range, please refer
248 to ``N-1``.  Each directory represents each monitoring target.
267 In case of ``fvaddr`` or ``paddr`` monitoring operations sets, users are
268 required to set the monitoring target address ranges.  In case of ``vaddr``
270 monitoring region to specific address ranges.  Please refer to the :ref:`design
273 For such cases, users can explicitly set the initial monitoring target regions
278 to ``N-1``.  Each directory represents each initial monitoring target region.
286 can set and get the start and end addresses of the initial monitoring target

585 Tracepoints for Monitoring Results
588 Users can get the monitoring results via the :ref:`tried_regions
590 snapshot, but it could be inefficient for fully recording all the monitoring
593 provides the whole monitoring results, while ``damon:damos_before_apply``
594 provides the monitoring results for regions that each DAMON-based Operation

613 Each line of the perf script output represents each monitoring region.  The

616 seventh field (``nr_regions=X``) shows the total number of monitoring regions
