+autotune_monitoring_intervals
+-----------------------------
+
+If this parameter is set as ``Y``, DAMON_RECLAIM automatically tunes DAMON's
+sampling and aggregation intervals.  The auto-tuning aims to capture meaningful
+amount of access events in each DAMON-snapshot, while keeping the sampling
+interval 5 milliseconds in minimum, and 10 seconds in maximum.  Setting this as
+``N`` disables the auto-tuning.
