+This option causes the aberrant behavior detection algorithm to reset
+for the specified data source; that is, forget all it is has learnt so far.
+Specifically, for the HWPREDICT B<RRA>, it sets the intercept and slope
+coefficients to unknown. For the SEASONAL B<RRA>, it sets all seasonal
+coefficients to unknown. For the DEVSEASONAL B<RRA>, it sets all seasonal
+deviation coefficients to unknown. For the FAILURES B<RRA>, it erases
+the violation history. Note that reset does not erase past predictions
+(the values of the HWPREDICT B<RRA>), predicted deviations (the values of the
+DEVPREDICT B<RRA>), or failure history (the values of the FAILURES B<RRA>).
+This option will function even if not all the listed B<RRAs> are present.
+
+Due to the implementation of this option, there is an indirect impact on
+other data sources in the RRD. A smoothing algorithm is applied to
+SEASONAL and DEVSEASONAL values on a periodic basis. During bootstrap
+initialization this smoothing is deferred. For efficiency, the implementation
+of smoothing is not data source specific. This means that utilizing
+reset for one data source will delay running the smoothing algorithm
+for all data sources in the file. This is unlikely to have serious
+consequences, unless the data being collected for the non-reset data sources
+is unusually volatile during the reinitialization period of the reset
+data source.
+
+Use of this tuning option is advised when the behavior of the data source
+time series changes in a drastic and permanent manner.
