112 This option causes the aberrant behavior detection algorithm to
113 reset for the specified data source; that is, forget all it is
114 has learnt so far. Specifically, for the HWPREDICT or MHWPRE-
119 it erases the violation history. Note that reset does not erase
120 past predictions (the values of the HWPREDICT or MHWPREDICT
124 present.
126 Due to the implementation of this option, there is an indirect
127 impact on other data sources in the RRD. A smoothing algorithm
128 is applied to SEASONAL and DEVSEASONAL values on a periodic
129 basis. During bootstrap initialization this smoothing is
130 deferred. For efficiency, the implementation of smoothing is
131 not data source specific. This means that utilizing reset for
132 one data source will delay running the smoothing algorithm for
133 all data sources in the file. This is unlikely to have serious
134 consequences, unless the data being collected for the non-reset
135 data sources is unusually volatile during the reinitialization
136 period of the reset data source.
138 Use of this tuning option is advised when the behavior of the
139 data source time series changes in a drastic and permanent man-
140 ner.
143 "rrdtool tune data.rrd -h in:100000 -h out:100000 -h through:100000"
145 Set the minimum required heartbeat for data sources 'in', 'out' and
146 'through' to 10'000 seconds which is a little over one day in data.rrd.
147 This would allow to feed old data from MRTG-2.0 right into RRDtool
148 without generating *UNKNOWN* entries.
151 "rrdtool tune monitor.rrd --window-length 5 --failure-threshold 3"
154 9 and the default failure-threshold is 7. This command now defines a
155 failure as 3 or more violations in a temporal window of 5 time points.
