If the specialized function R\bRR\bRA\bAs\bs exist for aberrant behavior detection,
they can be used to generate the graph of a time series with confidence
bands and failures.
LINE1:scaledlower#ff0000:"Lower Confidence Bound: Average bits out"
This example generates a graph of the data series in blue (LINE2 with
- the scaledobs virtual data source), confidence bounds in red (scaledup-
- per and scaledlower virtual data sources), and potential failures (i.e.
- potential aberrant aberrant behavior) marked by vertical yellow lines
- (the fail data source).

+ failures (i.e. potential aberrant aberrant behavior) marked by vertical
+ yellow lines (the fail data source).
The raw data comes from an AVERAGE R\bRR\bRA\bA, the finest resolution of the
observed time series (one consolidated data point per primary data
point). The predicted (or smoothed) values are stored in the HWPREDICT
R\bRR\bRA\bA. The predicted deviations (think standard deviation) values are
- stored in the DEVPREDICT R\bRR\bRA\bA. Finally, the FAILURES R\bRR\bRA\bA contains indi-
- cators, with 1 denoting a potential failure.

All of the data is rescaled to bits (instead of Octets) by multiplying
by 8. The confidence bounds are computed by an offset of 2 deviations

- The r\brr\brd\bdt\bto\boo\bol\bl _\bg_\br_\ba_\bp_\bh command is designed to plot data at a specified tem-
- poral resolution, regardless of the actually resolution of the data in
- the RRD file. This can present a problem for the specialized consoli-
- dation functions which maintain a one-to-one mapping between primary
- data points and consolidated data points. If a graph insists on viewing
- the contents of these R\bRR\bRA\bAs\bs on a coarser temporal scale, the _\bg_\br_\ba_\bp_\bh com-
- mand tries to do something intelligent, but the confidence bands and
- failures no longer have the same meaning and may be misleading.
