113 This option causes the aberrant behavior detection algorithm to

127 Due to the implementation of this option, there is an indirect
128 impact on other data sources in the RRD. A smoothing algorithm
129 is applied to SEASONAL and DEVSEASONAL values on a periodic
130 basis. During bootstrap initialization this smoothing is
131 deferred. For efficiency, the implementation of smoothing is
132 not data source specific. This means that utilizing reset for
133 one data source will delay running the smoothing algorithm for
134 all data sources in the file. This is unlikely to have serious
135 consequences, unless the data being collected for the non-reset
136 data sources is unusually volatile during the reinitialization
137 period of the reset data source.
139 Use of this tuning option is advised when the behavior of the
140 data source time series changes in a drastic and permanent
141 manner.
144 "rrdtool tune data.rrd -h in:100000 -h out:100000 -h through:100000"
146 Set the minimum required heartbeat for data sources 'in', 'out' and
147 'through' to 10'000 seconds which is a little over one day in data.rrd.
148 This would allow to feed old data from MRTG-2.0 right into RRDtool
149 without generating *UNKNOWN* entries.
152 "rrdtool tune monitor.rrd --window-length 5 --failure-threshold 3"
155 9 and the default failure-threshold is 7. This command now defines a
156 failure as 3 or more violations in a temporal window of 5 time points.
