Hi there,

Is there a plugin or feature of xymon that anyone knows of that allows one to do anomaly detection on the graph data? i.e. if there is nonstandard behavior on the graph that stands out, and you want it to be investigated.

Not natively, as Xymon is designed more around thresholding for alerting. However as metrics are stored in rrd files, a separate task could be built that read in rrds, calculates trends, and triggers status changes (man xymon | grep modify) for those tests based solely on future expectations.

Long term, visual options like those at http://hints.jeb.be/2009/12/04/trend-prediction-with-rrdtool/ might be useful as well.

HTH,
