Do you just want to use it to visualize anomalities, or do you want nagios to notify you if an anomality occurs? The pure visualization is pretty simple, I've already done that. Sadly the results were a bit - disappointing. After evaluating the graphs with aberrant behaviour detection we came to the conclusion, that about 99% of our nagios checks cannot be used to detect real anomalities. Things like diskfree, CPU, network i/o, disk i/o and the such do not follow strict patterns and are unpredictable most of the time. The only things we found ABD to be helpful with were monitoring temperature and humidity in our datacenters. PNP4Nagios can be easily used to implement ABD, all you have to do is change the rra.cfg to reflect the necessary aberrant behaviour detection RRAs. But keep in mind that you have to make those changes to the config _before_ the first RRD gets created, since you cannot add RRAs to existing RRDs - at least not without major knowledge in manipulating RRDs (say: export dump and manual import with selfmade scripts) Regards Sascha -- Sascha Runschke IT-Infrastruktur fon : +49 (201) / 102-1879 fax : +49 (201) / 102-1102105 mobil : +49 (173) / 5419665 GFKL Financial Services AG Vorstand: Dr. Peter Jänsch (Vors.), Jürgen Baltes, Dr. Tom Haverkamp Vorsitzender des Aufsichtsrats: Dr. Georg F.
