Hi Kennedy, the 'problem' is that rrdtool does not store the actual data but rather time-wise equi-spaced points on an interpolated curve ... with the pings this is a bit odd, as there is not realy a relationship between the second fastest ping in the first round and the second fastest ping in the second round ..., nevertheless it does work very well for drawing the 'smoke' but you should not try to read anything else into this data unless you have fully explored the inner workings of the Round Robin Database system and are sure the data does contain the information you are interested in ... cheers tobi -- ______ __ _ /_ __/_ / / (_) Oetiker @ ISG.EE, ETL F24.2, ETH, CH-8092 Zurich / // _ \/ _ \/ / System Manager, Time Lord, Coder, Designer, Coach /_/ \.__/_.__/_/ http://people.ee.ethz.ch/oetiker +41(0)44-632-5286 -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/smokeping-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
