Holt-Winters forecasting is a built-in feature of RRD.
It requires some 5 RRAs that store statistical data like deviation etc.
Then rrdgraph can visualize a confidence interval for each data
source and "optically alerts" you if the plot runs out of it.

See

First I wish to enhance nfsen in order to visually emphasize suspicious
traffic on main graph.
In the second stage nfsend could scan stored data and maintain an
alarm list like NERD (http://www.nerdd.org) with links that
points to the properly prepared graph.

This work is part of our activity in Geant Research Programme (GN2 JRA2).
