Dear Ladies and Gentlemen, It has finally dawned on this thick head that analysis of time series data is a 'Good Thing' and that there have been determined attempts to do so by
. Cricket (http://cricket.sourceforge.net/aberrant . Senior Deri (http://luca.ntop.org/ADS.pdf) Senior Deri's article refers to code downloadable from the Ntop site. I was hoping to see code - yep, opportunist is my name - to analyse the data from the RRD and conclude whether or not an anomaly is present, but couldn't find anything. The closest seems to be the RRD and Perl examples in the www directory of the Ntop distribution. Is there anywhere else I can look ? Has anyone had any experience with using Ntop as the collector for network time series data and the processing of that time series to determine if 'all is well' ? Please accept my apologies if this is letter is along the lines of "yeah that's really nice but can I have your wife and kids - and your house and money as well ?". The main reason for it is to focus on using Ntop to detect anomalies. Once again, if the state of the art is: . use Ntop as a collector and harvest the measurements from it . store the measurements in an RRD (because that is simply the standard method of doing so) and then . dump it and analyse it according to what part of the massive time series literature one is clever enough to recognise and code then please let me know. This is really an exciting prospect. Thank you very much for putting this much of the solution - in the wonderful ntop engine - in front of me. Perhaps this is an infinitismal part of Mr Strauss's reply to 'Ruth' about modelling traffic ? In any case, I happy to be the most stupid understudy to the Strauss Besso for Senior Deri (see 'Einstein for beginners'). Yours sincerely. -- ------------------------------------------------------------------------ Stanley Hopcroft ------------------------------------------------------------------------ '...No man is an island, entire of itself; every man is a piece of the continent, a part of the main.
