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 http://oss.oetiker.ch/rrdtool/doc/rrdcreate.en.html http://oss.oetiker.ch/rrdtool/doc/rrdgraph.en.html as well as http://www.usenix.org/events/lisa00/full_papers/brutlag/brutlag_html/index.html http://cricket.sourceforge.net/aberrant/rrd_hw.htm http://www.itl.nist.gov/div898/handbook/pmc/section4/pmc435.htm 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). Regards Gabor ------------------------------------------------------------------------- Using Tomcat but need to do more?
